ABSTRACT:
The first limb of astanga yoga is yama (self restraint). Its aphorisms were refined and reframed in the form of psychological self restraint health and wellness scale. The objective of the paper is to test the hypothesis; “Management of health and wellbeing through self restraint yoga measures”. Samples of 1,153 students aged 11-18 years were selected from 20 secondary schools in Bhopal region, India. We used SPSS and AMOS version 25 exploratory and confirmatory factor analyses to test the validity and reliability of yoga self-restraint scale (YSRS). The final YSRS scale comprises 27 items which has five sub-domains (non violence, truthfulness, non-stealing, celibacy and non possessiveness) with Cronbach’s alpha of 0.74, variance 58.46%. YSRS results were found to be significant at p<0.001. Goodness of Fit indices calculated from the scores is within the accepted range confirming the validity of the model. Exploratory and confirmatory factor analyses supported a one-dimensional factor structure of the YSRS. Yoga self restraint scale with 27 items is valid and reliable measure for wellbeing of oneself and society. There is a scope for further research work in the other main domains of yoga concept.

INTRODUCTION:
Most of the concepts on self restraint in the western psychological research were restricted up to the level of food habits–diet controls restraint. The latest studies carried out by Kkeli N[1] reveals that the calorific value splurges scale were developed as a part of the psychological instrument. Obesity self restraint measures were also studied by Van Strien T[2]. Some studies on self restraint relation to maturity[3] were also made. Obviously, these dietary scales and obesity studies results have led to the studies of well being[4].
In this paper we have elaborated the concept of self restraint through Indian yoga sciences[5]. The concept of self restraint or yama is explained and discussed in the Indian yoga text booksin the form of aphorisms as “ahimsa satyaasteyabrahmacharyaaparigrahayama”[6,7] It may be translated as non-harming (ahimsa), truthfulness (satya), abstention from stealing (asteya), walking with awareness (brahmacharya), and non-possessiveness (aparigraha) and thesefive principles are called mahavratam (great vow) when they are followed universally without the any restriction of class, place, time, and circumstances[8]. The qualitative explanation of these five principles[9, 10, 11] of yama: ahinsa: restricts any types of violence not only by self but also towards society. Satya is an essential requirement of healthy personal & social life without which formation of a faithful society is impossible[12]. Asteya: is essential for corruption free society[13]. Brahmacharya is walking with awareness and self study for higher order things[14]. Aparigraha is non possessiveness of any resources than what is required for one self[15]. It’s also sets an example for all the members of the society[16].
Self restraint has been given a different interpretation by defining it as a suppression of egoistic desires and distress[17] and its scale is developed as super ordinate dimension of self reported adjustment. Self restraint has significant role in self-control, social health and well being[18,19].Linking self restraint’s five vows which not only brings individual wellness but also creates the foundations for healthy behavioral society[61-65], self-esteem, interpersonal skills and educational attainment[20], Self development values can improve Psychological problems of individuals especially adolescent groups[21,22,23]. Yoga Self restraint regulates emotions, thought, behaviors towards well-being and social bonding[24]. Well being of the society and individual includes various parameters such as life satisfaction, happiness, self regulation and moral observances[25-31], In all the above references there was no mention of standardization of scale development for the yoga concept of self restraint. Hence, we conceptualized, developed and carried out the psychometric analysis for five items of self restraint and tested for its validity and reliability. With these moral and physical benefits/values of the individual, how it gets benefited to the society, a sense of connectedness through one’s own personality may be compared with the western concept of behavioral traits. Based on the above conceptualization process of yoga self restraint or yama, the hypothesis may be stated as,
HYPOTHESIS:
We hypothesized that yoga self-restraint may be related to social health and wellbeing.
Conceptual Frame:
The conceptual frame work of yoga self restraint is designed based on five principles relation with self and society’s well being. The basic five codes of yama are non-violence, truthfulness, non-stealing, celibacy, and non-possessiveness [32]. These codes of conduct covers the ethical commandments or guidelines that deals with underlying principles governing one’s own development and also with other human beings. The aphorisms[33] related to yama are used in designing the frame; Ahimsa pratishthayam tat sannidhovaira-tyagah (practice of non injury affects other people who come near to the practitioner will naturally lose any feelings of hostility), satyapratishthayam kriyaphalaashrayatvam (As truthfulness is achieved, the fruits of actions naturally result according to the will of the practitioner), asteyapratisthayamsarvaratnaupasthanam (When non-stealing is established, all wealth comes on its own), brahmacharyapratisthayamviryalabhah (When walking with awareness of the highest reality is firmly established, then a great strength, vitality is acquired), aparigrahasthairyejanmakathantasambodhah (When one is steadfast in non-possessiveness with the senses, there arises knowledge of the why and how of past and future).
Fig 1: Yoga Self-restraint frame domain
The frame shows five principles of self restraint in the outermost circle, its benefits to individual and society wellness are shown in the second and third circles (Fig. 1). In the literature[66-69], the benefits are related to value systems. In a way these may be comparable to the benefits of yama. The values are given as “don’ts” in one’s life.
Method:
Sampling:
A sample size of 1,153 individuals was selected based on convenient sampling basis. DeVellis RF[34] recommends a ratio of 1:15 or 1:20 as an ideal sample size. Learning from the literature, a sample size of greater than 200 was decided to ensure the sample adequacy. The study was conducted in Bhopal city of Madhya Pradesh state, India. An age group of 10-18 years participants was considered as the criterion for inclusion in the study. The individuals who consented to provide data were considered in the sample size selection. The data were collected from 5 April to 4 May 2018.
The study was conducted among in Bhopal region of Madhya Pradesh state, India. Schools, which have Yoga as a part the curriculum, were considered for selection. Out of 52 secondary schools with Yoga curriculum in the region, 20 were selected randomly. In India, Yoga is included in the curriculum from sixth standard. Hence, students studying six and above standards were considered for selection of sample. From the each selected school, students who consented to participate in the study and provide information were included. DeVellis, R. F., (2016) recommends a ratio of 1:15 or 1:20 as an ideal sample size. Going by this criterion, a sample size of greater than 540 is adequate since the initial pool of items was 50. We selected 1,153 students with their consent to test psychometric properties. The data were collected from 5 April to 4 May 2018. The demographic details of the subjects are given in Table 1.
Procedures of scale development:
Scale development is a systematic process that is carried out at different stages of analysis. Following recommendations of DeVellis RF[34] and Pasquali L[35] scale development for the present study was accomplished in three stages viz; item generation, theoretical analysis and psychometric analysis.
Content domain was specified through review of literature related to yoga self restraint specified in yoga philosophy. Among the eight limbs of yoga, the self-restraint conceptual model (Fig.1) that relates beliefs with social health and wellbeing [36, 37] was considered to specify the content domain. The model comprises of five concepts namely non-violence, truthfulness, non-stealing, celibacy, and non-possessiveness[36], the researcher considered all five concepts as the constructs for scale development. Item pool generation provides a conceptual endorsement for the initial item pool[38]. The present research employed combination of deductive and inductive methods of initial item pool generation as recommended by Kapuscinski AN and Masters KS[39]. The researchers reviewed literature related to the Health Benefit Model, Yoga self restraint and social health behavior to acquire basic comprehension about the concept and take leads for developing constructs and items. The researchers also interacted with experts in the fields of yoga science and obtained qualitative information regarding the content domains and objective of the research. The information was analyzed and related with the concept of yoga self restraint to generate pool initial items. As a result, 50 items were developed under the selected content domains. Items worded negatively for the construct were reverse coded and scored. Following the recommendations by[34,35,40] parameters such simplicity, clarity, specificity, capability to ensure variability of response and freeness from bias of the items were carefully considered while drafting the items.
Theoretical analysis:
Content validity:
Content validity of the initial items was assessed to make sure that the items are representative of the identified construct i.e. Yoga self restraint[32]. The researchers, in order to assess content validity of the initial items clearly defined the conceptual framework (Fig.1) of yoga self restraint by undertaking a thorough literature review and seeking expert opinion. The expert panel comprised of 4 experts; one Vedic philosophy expert from Texas, USA, another expert from alternative and complementary medicine, All India Institute of Medical Sciences, Rhishikesh, statistical expert and a psychology professor Sastra university, yoga expert from University of Patanjali, Haridwar, India. The experts assessed the relevance of items in relation to the content domain applying a tool namely Content Validity Index (CVI) developed by Waltz[41]. The experts rated each item against a four-point scale (1=Note relevant, 2= Somewhat relevant, 3=Quite relevant and 4=Highly relevant). A score of 3 or 4 indicates that the content represented by each item was considered valid and in harmony with the theory that is being measured and they are retained. The items which received score 1 or 2 were rejected from the scale indicates that the theoretically or practically irrelevant questions or any ambiguous items that apparently repeated the essential content of other items.
Face validity:
Visual appearance of the tool such as consistency of the style, formatting, readability and feasibility as prescribed by Devon HA[42] were tested by applying the initial level scale with 40 individuals. The respondents were asked to judge the user-friendliness of the tool. Feedback from the respondents was incorporated to improve the tool. This process was helpful to assess ambiguity and skewedness i.e. respondents providing very similar answer to all the items.
Psychometric analysis:
The psychometric analysis involves a number of quantitative techniques to test construct validity and reliability of the scale. Construct validity according to Posakoff PM[43] is the quantity to which interpretation can be meaningfully constructed from the observed scores to the hypothetical constructs about which the observations are meant to hold information. In addition to construct validity, convergent validity, criterion validity and discriminate validity of the scale were tested quantitatively. DeVellis RF[34] strongly recommends the combined use of Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) to achieve consistent results of the psychometric indices. Hence, these validity tests were done using EFA and CFA. Reliability, a quantification method producing the consistent results on recurring examinations[34] was measured in terms of indicators namely Cronbach Alpha, Spearman-Brown coefficient, composite reliability and average variance extraction. Concurrent validity was assessed by calculating the correlation between the scores of the present scale and an established scale namely Yoga Self Efficacy Scale.
In this study the scale was with five options ranging from ‘strongly disagree’ (score 1) to ‘strongly agree’ (score 5). Each of the items in the scale is an agreement statement on the five point Likert scale[44], which is a quantitative technique meant for measuring psychological variables like attitude, perception, anxiety, stress, beliefs etc. All the items in the scale were positively stated about Yoga self restraint. The summated score of all the items was treated as the quantifiable measure of the construct and it was considered for all quantitative analytical purposes. All items included in the Likert scale were considered as continuous variables. The scale was prepared in English and Hindi to facilitate respondents’ comprehension over the statements. The questionnaire was filled by the respondents. Factors are extracted and a factor structure including the correlation between the factors is proposed by EFA. The proposed factor structure is hypothesized and tested in CFA. It the statistical results fits with the hypothesized model the researcher can conclude that the factor structure is valid[45]. Hence, the study evaluated the scale using both EFA and CFA. IBM SPSS 25 software version was used to calculate descriptive statistics, correlation matrix, EFA and Cronbach Alpha value. IBM SPSS Amos 25 software version was used to perform CFA. Convergent validity was verified using the Average Variance Extracted, a statistic calculated from values of factor loads. Construct validity was assessed by computing model fitness indices namely p value of Chi square, RMSEA, GFI, AGFI, CFI, TLI, NFI and Chisq/df which were the outputs of confirmatory factor analysis. Discriminate validity was examined by measuring the level of redundancy of items through Modification Indices (MI).
RESULTS:
A sample size of 1,153 healthy participants was selected for the study from the different cross sections of the society to test the psychometric properties of the YSRS. They were adolescents (mean age of 14±4 SD) covering both male 571 (49.52%) and female 582 (50.48%) populations. Among the total participants 96.21% practiced yoga as a theory and practical subject. The demographic details of the subjects are given in Table 1.

We developed the instrument for yoga self restraint on the lines of methodology given by Montero I & León OG[40]. As a result based on the conceptual frame work of yoga self restraint (Fig 1), 50 items were developed under the selected major content domain viz; yoga self restraint. We divided the 50 items into five sub domains such as non-injury (10 items), truthfulness (10 items), abstention from stealing (10 items), living with awareness of the highest reality (10 items), and non-possessiveness (10 items) were generated as the initial pool of items.
The initial item pool consisting of 50 items was vetted by four experts to assess the degree to which the items taken together constitute an adequate operational definition of a construct[41] i.e. content validity. The experts reviewed the initial item pool using a CVI rating tool. CVI was calculated following the recommendation of Waltz C[41]. The experts gave their rating individually. Then, for each item, the index was calculated as the number of experts giving a rating 3 or 4 and this was divided by total number of experts. The items for which the index was less than 0.75 were considered to be irrelevant eliminated from the original list. From the initial pool, 11 items on the draft YSRS were deemed to be invalid because they yielded CVIs of 1/4=0.25 to 2/4=0.50 and were removed with CVI lower than 0.75[46], All the remaining items were valid with CVIs ranging from 0.75 (3/4) to 1 (4/4) and were retained which resulted in a 39-item questionnaire. After modifying the scale based on rating by the experts, the scale was individually administered with 40 persons who regularly practiced Yoga. Each statement was read out to the respondent and in reply, the respondent stated what he/she understood from the item. If the content what the respondent comprehended and what had been conceived by the researchers matched, the item would be considered to be qualified. If mismatch was identified, the researcher was asked, “Why did you mean the statement like this?” The response would uncover issues present in the items like vagueness, ambiguity, leading words/sentence, unfamiliar words, complicated sentence, closed ended statement, sensitive statement etc. Based on this information, statements were rephrased. The modified statements were once again read out to the respondent and feedback was received and accordingly modified. The 39 items developed after content validity testing and cognitive interviews with select respondents.
The scale evolved after theoretical analysis with 39 items was administered to 1,153 participants. Exploratory factor analysis was conducted using the scores obtained from the survey. The Kaiser–Meyer-Olkin (KMO) measure was used to assess the sample adequacyand to prove the correlation matrix is an identity matrix Bartlett's Test of Sphericity is calculated. KMO value was 0.61which enabled further item reduction. Following the EFA, 12 items were excluded from the 39-item scale, which resulted in 27-items and five factor variables with KMO value was 0.85 and It was significant (p<0.001). Bartlett’s Test of Sphericity value which tests association between the variables was χ2=12836.55 and it was significant (p<0.001).
Maximum Likelihood Analysis method of factor extraction with Promax Rotation was used and five factors were extracted explaining 58.46% within 1σ of the total variance. Results of the Scree plot technique indicated extraction of five factors from the 27 variables. Factor loading measures ranged from 0.45 to 0.87. Since all the factor load values of all the 27 variables were greater than 0.45, all of them were retained in the scale for next level confirmatory factor analysis. Table 2 shows variance contributed by each factor and their corresponding Eigen values.

Note. Extraction Method: Maximum Likelihood. Rotation Method: Promax. Only factor loadings greater than .40 are reported, in order to aid interpretation of the factor structure. Kaiser-Meyer-Olkin Measure of Sampling Adequacy: 0.85.
To undertake the most appropriate interpretation, the loading values were carefully examined using Hair [47] guideline for practical significance, which indicates a factor loading of ±0.3 for which the item is of minimal significance, ±0.4 indicates it is more important, and ±0.5 indicates the factor is significant.
The researchers conducted a CFA applying a structural equation modeling to test a hypothetically developed factor structure through EFA with five latent factors and 27 observed variables. The model obtained from confirmatory analysis is presented in Fig 2.
Fig. 2 Yoga self restraint model through CFA Abbreviations; AS=Asteya, S=Satya, AP=Aparigraha, AH=Ahinsa, B=Brahmacharya
The hierarchical model shown in Fig.3 was retained as the model with the good fit because it indicates that each of the five factors were interrelated with first-order and second order extracted factors termed as health and wellbeing through yama (WBtY).
Fig. 3 Hierarchical model of YSRS for wellness (WBtY)
Retention of this model is supported by the assumption that these five sub domains led to one larger scale[49]. The model shows factor loading values and the standardized maximum likelihood parameter estimates (path coefficients) with strong correlations.
Construct validity:
In confirmatory factor analysis many indices of model fitness are used to test construct validity. Hair JF[48] recommends to use at least one index from model fit categories namely absolute fit, incremental fit and Parsimonious fit. Results obtained in the present study on model fitness indices are presented in Table 3.

Table 3 illustrates three different types of indices viz; absolute, incremental and parsimonious values. All three indices minimum level was achieved[49].
Convergent validity:
We performed three additional factor extractions to confirm the model structure, presented in Table 5. This table shows item quality (Chi-square), composite reliability (CR), and average variance extraction (AVE) were quantified to test convergent validity. Statistical significance of all the items in the model indicates presence of convergent validity. All factors had values of .50 or higher, demonstrating that the observed variable sufficiently reflected its construct’s latent variable[50]. Factors with a CR of .96 were considered good[51], and all factors appropriately exceeded this level. The acceptable AVE of 0.50 ranged between .40 and .69[52]; all five–order factors demonstrated values within this range, exhibiting good strength.
Concurrent validity
A Yoga Self Efficacy Scale (YSES) developed by Birdee GS[37] with 3 constructs and 12 items was selected to test concurrent validity of the present scale. YSES has been developed to measure self-efficacy among the practitioners of Yoga. The tool has been evolved based on the theory of self-efficacy. YSES has robust internal consistency with Cronbach’s alpha value of 0.93 and good construct validity measures. When the scale was administered in our study, it had Cronbach’s alpha value of 0.876. The scores of the scale developed in the present study were correlated with YSES. Since the data were not normally distributed, non-parametric tool of association measurement namely Spearman’s correlation coefficient was applied. Both the scores were positively correlated (ρ=0.87) and it was significant (p<0.001). Presence of criterion validity was proved due to positive and significant correlation coefficient between the newly developed scale and an established scale.
Reliability:
Internal consistency of the 27 item five factor scale was determined by calculating Cronbach’s alpha measure and composite reliability measure. The Crobbach’s alpha value was 0.74. Composite reliability measure was 0.96.
Test-retest reliability:
was carried out for a month’s time in 304 participants. The Intra-class correlation coefficient (ICC), Cronbach’s alpha and one-sample statistics was used to calculate the test-retest reliability. ICC of average measures was ranged from 0.76 to 0.93 for entire scale was 0.75 considered an adequate reliability score[53]. The Overall scale reliability for the items was better, with Cronbach’s alpha for the subscale ranging from .76 to .94 and over all being .74 for the entire scale. These results confirmed that five factor YSRS has good stability. Test-retest analysis data mean 3.87 with t-value 71.42 were same over a month’s time showed better consistency.
DISCUSSION:
Systematic steps as prescribed in the literature of psychometric research were adopted to develop this instrument. The yoga self-restraint scale concept developed based on ancient Indian yoga philosophical texts as an extensive literature review (deductive method) and consulted with relevant people about the subject (inductive method)[54]. The initial item pool, which had 50 items got reduced to 27 items with five constructs at the end of the study. It has been validated and found to be reliable by using the psychometric analysis. The stated hypothesis that yoga self restraint may be related to social health and wellbeing has been proved with final five regression coefficient values (Table 5). These coefficients were calculated using EFA and CFA statistical analytical techniques on the lines of Barry[55] to assess the influence of self restraints on social health and well being. In terms of scale’s validity, reliability and factor structure of YSRS. The results of this study suggest that the YSR Scale is providing an appropriate instrument for measuring the Social wellness among adolescents and support the factor structure, reliability, and validity of the measures. We identified five factors of the YSRS scale and these fit the hierarchical model: ahimsa, satya, asteya, brahmacharya, aparigraha.
Each of these five factors exhibited good internal reliability and constituted a model with a good fit (GoF) with the data. The research community, over the years, has developed a number of GOF Indices to test the construct validity. The GoF Indices are categorized into three groups namely absolute fit indices, incremental fit indices and parsimonious fit indices. Absolute fit indices are a quantity of degree of fitness of the model to the empirical data. They offer the most fundamental measure of the fitness[47]. Goodness of Fit Index (GFI) is another absolute fit index. According to Tanaka JS & Huba GJ[56] GFI is equivalent to R2 in regression analysis. In the lines of R2 measure, for GFI also Adjusted index is calculated (AGFI). Root Mean Square Error of Approximation (RMSEA) is a population based index and is less sensitive to sample size. Tucker Lewis Index (TLI) has values range between 0 and 1. Models with values close to 1 show better fit. Likewise, Normed Fit Index (NFI) values range from 0 to 1 and values above 0.90 indicate better fit (Song, H. J., et al. 2011). According to Hair, J. F., et al. (2010) a parsimonious model is significant to prove that the postulated model fits the data in comparison with a complex model. According to Wheaton57 the ratio of Normed Chi square/df is reasonable. The ratio obtained in the present study was 3.67 and hence it could be inferred that the value is reasonable to judge that the model has parsimonious fitness. The results of this study suggest that the YSR Scale is providing an appropriate instrument for measuring the Social wellness among adolescents and support the factor structure, reliability, and validity of the measures. We identified five factors of the YSRS scale and these fit the hierarchical model: ahimsa, satya, asteya, brahmacharya, aparigraha. Each of these five factors exhibited good internal reliability and constituted a model with a good fit with the data. Those five factors were moderately correlated with each other, suggesting that they each assess related, although distinct, components of Yoga self restraints or yama.
The 27-item YSRS is a short scale that can be administered both for general population and for school setting. The age appropriateness is compared with the adolescent psychiatry of the quality of life[58]. The psychometric quality of the YSRS are generally comparable to the pattern matrix, goodness of fit and factor loadings of the CFA analysis carried out by Huang CH[59]. Van den Berg PT & Pitariu H[60] has brought out a relationship between wellbeing and personality during societal change. The YSRS scale are positively and significantly correlated with the standardized scale of Birdee’s[37] Yoga Self-Efficacy Scale to prove existence of concurrent validity.
CONCLUSION:
A yoga Self-restraint scale is described to measure social health and analyze its relation with five self-restraints; non-injury, truthfulness, abstention from stealing, living with awareness of the highest reality, and non-possessiveness. We employed both qualitative and quantitative methods to develop and validate an YSR scale using SPSS and AMOS version 25’s exploratory and confirmatory factor analyses for 1,153 general populations from Bhopal city, India. The standardized estimated regression value is found to be 0.67 which is greater than the required level of ≥ 0.5 and thus showing a good relation between five restraints of yoga to social health and wellbeing of the adolescents. This yoga instrument can facilitate and provide a social health care and wellbeing: self-esteem, interpersonal skills, healthy behaviors, educational attainment. The present study has been undertaken in a cross sectional setting with limited number of samples. There is a scope for further research in the field of eight limbed yoga.
