Coaching Servant Leadership: Scale Development and Validation.

This study aimed to develop a valid and reliable scale for measuring coaching servant leadership in different contexts (Japan and the United States). First, potential items were collected in Japan using both deductive (i.e., literature review) and inductive (i.e., surveys among 103 coaches and 34 university students) approaches and narrowed down via content validity assessment by 10 experts. Next, quantitative studies were conducted to validate the scale's construct validity, among 936 high school athletes from Japan. Finally, the scale's applicability to the US context was demonstrated, among 278 university athletes in the US. The analyses resulted in a six-factor model with 17 items to assess coaching servant leadership behaviors: (1) acceptance; (2) shared vision; (3) empowerment; (4) dedication; (5) humility; and (6) winning second. In conclusion, this study developed a coaching servant leadership scale by applying both deductive and inductive approaches and deemed it applicable not only in Japan but also in the US. It is anticipated that future studies will examine the impact of coaching servant leadership on athletes in detail, with findings applied in practice for the development of coaches.

Assessment of "los pequeños" Big Five: The Spanish version of the Big Five Personality Trait Short Questionnaire in adolescents.

The major advantage of the Big Five Personality Trait Short Questionnaire (BFPTSQ) over other noncommercial Five-Factor Model (FFM) personality scales is that it targets both adolescents and adults. The aim of the present study was to explore the psychometric properties of this questionnaire in a Spanish, adolescent sample. The main sample was composed of 1,082 participants (Mage = 14.16, SD = 1.56, age range = 12-17 years), 53% girls. The results showed that the expected factor structure was mostly recovered using exploratory structural equation modeling (ESEM). The ESEM presented satisfactory fit indices, as well as metric invariance and partial scalar invariance across genders. Moreover, coefficient αs and ordinal Ωs of all the scales were over .70, and test-retest indices were significant (p < .001). Regarding the associations of BFPTSQ with a junior FFM inventory, the correlations with the broad-trait scales ranged from .61 to .72, and 29 out of 30 correlations with the facet scales were significant (p < .001). Finally, most of the expected associations between the BFPTSQ scales and the criterion measures (internalizing and externalizing symptom scales, life satisfaction, and academic performance) were confirmed, widely replicating the results found in the development of the original questionnaire. This study supports the construct validity of extraversion, agreeableness, conscientiousness, and emotional stability scales in Spanish-speaking adolescents. However, openness did not emerge as a well-defined factor in the present sample. The questionnaire seems to be a useful and readable measure for research and, potentially, for other applications such as clinical use. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Development of Mindset Theory Scale (Growth And Fixed Mindset): A Validity and Reliability Study (Turkish Version)

This study aims to develop a valid and reliable measurement instrument to measure the quality of Mindset Theories of students aged 14- 22. A systematic approach was followed to develop the measurement tool. 1145 students participated in the study (48% were female and 52% were male). Exploratory and confirmatory factor analysis were applied to determine the scale's construct validity. As a result of exploratory factor analysis, the scale was determined to consist of 19 items and four sub-dimensions. In line with the literature, these dimensions are called Procrastination, Immutability of Belief, Belief in Improvement and Effort. The four-factor structure of the scale was confirmed by confirmatory factor analysis. In addition, it was found that the differences between the averages of the upper and lower groups that make up 27% of the scale items are significant. When the results of the reliability analyses were examined from the perspective of the factors of the mindset theory scale, the values of 0.724 for the Procrastination sub-dimension and 0.805 for the Immutability of Belief sub-dimension of the Fixed Mindset dimension were found. It was found 0.701 for the sub dimension of Effort and 0.771 for the sub dimension of Belief of Mindset Theory Scale’s Growth Mindset dimension. The internal consistency coefficient was found 0.723 for the Fixed Mindset dimension and 0.714 for the Growth Mindset dimension of the Mindset Theory Scale. These results shows that the Mindset Theory Scale measures students' mindset theories in a valid and reliable way.

Assessment of Population Well-being With the Mental Health Quotient: Validation Study.

BackgroundThe Mental Health Quotient (MHQ) is an anonymous web-based assessment of mental health and well-being that comprehensively covers symptoms across 10 major psychiatric disorders, as well as positive elements of mental function. It uses a novel life impact scale and provides a score to the individual that places them on a spectrum from Distressed to Thriving along with a personal report that offers self-care recommendations. Since April 2020, the MHQ has been freely deployed as part of the Mental Health Million Project.ObjectiveThis paper demonstrates the reliability and validity of the MHQ, including the construct validity of the life impact scale, sample and test-retest reliability of the assessment, and criterion validation of the MHQ with respect to clinical burden and productivity loss.MethodsData were taken from the Mental Health Million open-access database (N=179,238) and included responses from English-speaking adults (aged≥18 years) from the United States, Canada, the United Kingdom, Ireland, Australia, New Zealand, South Africa, Singapore, India, and Nigeria collected during 2021. To assess sample reliability, random demographically matched samples (each 11,033/179,238, 6.16%) were compared within the same 6-month period. Test-retest reliability was determined using the subset of individuals who had taken the assessment twice ≥3 days apart (1907/179,238, 1.06%). To assess the construct validity of the life impact scale, additional questions were asked about the frequency and severity of an example symptom (feelings of sadness, distress, or hopelessness; 4247/179,238, 2.37%). To assess criterion validity, elements rated as having a highly negative life impact by a respondent (equivalent to experiencing the symptom ≥5 days a week) were mapped to clinical diagnostic criteria to calculate the clinical burden (174,618/179,238, 97.42%). In addition, MHQ scores were compared with the number of workdays missed or with reduced productivity in the past month (7625/179,238, 4.25%).ResultsDistinct samples collected during the same period had indistinguishable MHQ distributions and MHQ scores were correlated with r=0.84 between retakes within an 8- to 120-day period. Life impact ratings were correlated with frequency and severity of symptoms, with a clear linear relationship (R2>0.99). Furthermore, the aggregate MHQ scores were systematically related to both clinical burden and productivity. At one end of the scale, 89.08% (8986/10,087) of those in the Distressed category mapped to one or more disorders and had an average productivity loss of 15.2 (SD 11.2; SEM [standard error of measurement] 0.5) days per month. In contrast, at the other end of the scale, 0% (1/24,365) of those in the Thriving category mapped to any of the 10 disorders and had an average productivity loss of 1.3 (SD 3.6; SEM 0.1) days per month.ConclusionsThe MHQ is a valid and reliable assessment of mental health and well-being when delivered anonymously on the web.

Measurement Properties for a Scale Assessing Self-Regulation in Parents and Parenting Practitioners

Parenting self-regulation is increasingly recognised as an important facet of positive parenting, as it allows parents to manage their thoughts, behaviours, emotions and attention in order to effectively carry out parenting tasks. Evidence-based parenting programmes such as the Triple P-Positive Parenting Program aim to increase parenting self-regulation by teaching parents a range of skills and strategies to deal with everyday parenting. Despite the importance of self-regulation within the field of parenting, few measures assessing this construct are available. The current investigation aims to add to existing literature by evaluating the measurement properties of a brief and parsimonious measure of self-regulation for both parents and parenting practitioners, the Parenting Self-Regulation Scales (PSRS)—Parent and Practitioner versions. Exploratory and Confirmatory Factor Analyses gave support for a single-factor model for the parent version, and this was confirmed in the practitioner version. Both versions demonstrated excellent internal consistency and hypothesis testing supported the construct validity of both scales. The results indicate that the PSRS is a promising brief measure of parenting self-regulation for parents and practitioners which could prove useful to both clinical work and research in the parenting field.

Adaptation and Validation of the Lithuanian-Language Version of the Olympic Value Scale (OVS).

Background: The Olympic Games is one of the biggest sports events which should express and promote Olympic ideals. Aiming to generate more insights on the expression of Olympic Values, the Olympic Value Scale (OVS) was developed to assess how people perceive values in relation to the Olympic Games. The aim of the present study was to examine the validity and reliability of the Lithuanian version of OVS (LT-OVS). Methods: The scale construct validity and reliability was tested using a sample of 365 university students (mean age 22.02, SD = 6.58; 49.9% male). After the evaluation of the scale structure, convergent and discriminant validity as well as reliability of the scale were evaluated by assessing composite reliability and average variance extracted (AVE), examining the square root of the AVE. For further validity analysis, associations between the LT-OVS factors and other variables were examined. Results: The original OVS captures three dimensions, which are appreciation of diversity, friendly relations with others, and achievement in competition. Exploratory and confirmatory factor analyses confirmed the original three-factor structure of the OVS. The internal consistency values for all three subscales of the LT-OVS were 0.80 and higher. Convergent and discriminant validity criterions were met. Relations between the LT-OVS dimensions and attitudes towards fair play and Olympic Games were also revealed and discussed. Conclusions: This study makes a contribution by confirming the validity of the LT-OVS and encouraging future adaptation of it into other cultures and research on Olympic Values.

Development and Validation of an Interprofessional Collaboration Scale for Home Health Care for the Frail Elderly

The purpose of this study was to develop an interprofessional collaboration (IPC) scale for home health care for frail elderly. The first items of the IPC scale included collaboration members' attitudes, awareness, motivation, team strength, communication, relationships, information, care recipients' interests, effects, development, utilization of social resources, contributions to the community, and crisis management. The subjects were 512 care managers who work in home care support offices across Japan. They manage interprofessional collaboration in home health care for frail elderly who need care at 65years old and above. The scale's construct validity, internal consistency, the validity of known groups, concurrent validity, and test-retest reliability (193 subjects) were examined. The final IPC scale's items consisted of four factors (37 items): the strength of interprofessional teams (16), the management of collaborative systems (7), effects of collaboration (8), and communication (6). Four factors explained 58.6% of the total explained variance. The modified model fit of the scale achieved acceptable levels. The Cronbach's α coefficient for all items was .97. The sum of communication factor in the cities/wards group was lower than those in the towns/villages group. There were differences between the sum and each factor with different levels of ease to collaborate. The intraclass correlation coefficient for all items in the first and second assessments was .875. The validity and reliability of the IPC scale have been verified. This scale can be used to assess the IPC for home health care for frail elderly.

Reliability and Construct Validity Assessment of Wong and Law Emotional Intelligence Scale and Satisfaction With Life Scale in the Indian Hospitality Industry.

Organizations today require employees who are well at managing emotional intelligence and using their emotions in a constructive process. The present study considered the Satisfaction with Life Scale (SWLS) and Wong and Law Emotional Intelligence Scale (WLEIS) for the study. WLEIS has four factors: self-emotional appraisal (SEA), other's emotional appraisal (OEA), regulation of emotion (ROE), and use of emotions (UOE). These scales help to manage emotions that result in satisfaction with life. The purpose of the study is to validate WLEIS and SWLS because this scale has been validated across many countries but very few studies have been conducted in the Indian context. Apart from that, the current study also incorporated SWLS to validate constructs and measurement models. A sample of 238 participants working in the hospitality industry have been considered for the study. Exploratory factor analysis and confirmatory factor analysis were used to validate all the constructs and measurement models. The three factors of WLEIS and SWLS showed Cronbach's α more than 0.8 that showed excellent internal consistency except for SEA. The results of exploratory factor analysis found that eigenvalue ranged from 2.8 to 5.9, and the total variance explained by constructs was 65.9%. Confirmatory factor analysis showed average variance explained of each construct to be 0.5, and composite reliability to be more than 0.7, which shows excellent construct validity of scales in the Indian hospitality sector. The study also validates measurement research model of WLEIS and SWLS on the basis of model fit index (chi-square/df = 4.83, RMSEA = 0.10, GFI = 0.94, and CFI = 0.90). The strong validity and reliability of the WLEIS and SWLS have proved that neuroscience can apply these scales to measure emotional intelligence in order to understand others' emotions and apply emotions in a constructive process that may lead to satisfaction with life.

Sport Psychological Skill Factors and Scale Development for Taekwondo Athletes.

The purpose of this study was to identify the sport psychological skills of Taekwondo athletes and to develop a scale measuring such skills. We collected preliminary data using an open-ended online survey targeting Taekwondo athletes from nine countries (South Korea, China, Malaysia, United States, Spain, France, Brazil, United Kingdom, and Taiwan) who participated in international competitions between 2019 and 2020. We extracted participants’ sport psychological skills from 75 survey responses, guided by expert meetings and a thorough literature review. We verified our Taekwondo psychological skill scale’s construct validity using 840 survey responses. We utilized V coefficients, parallel analysis, an exploratory structural equation model, maximum likelihood, confirmatory factor analysis, and multi-group confirmatory factor analysis for data analysis. We identified six core sport psychological skills: “goal setting,” “confidence,” “imagery,” “self-talk,” “fighting spirit,” and “concentration.” Our final measure, which demonstrated evidence of reliability and validity, comprises 18 items spanning 6 factors, with each item rated on a 3-point Likert scale.

Construct validity of the Cigarette Ratings Scale and associations with tobacco use and product feature outcomes

BackgroundSubjective ratings are inconsistently associated with behavioral outcomes such as tobacco use and there is no current standard. The Cigarette Ratings Scale is an ideal measure for further evaluation because it has been widely used in tobacco regulatory science and tobacco industry research. PurposeThis study investigated the construct validity of the Cigarette Ratings Scale and associations with tobacco use and product feature outcomes. MethodsUsing secondary analysis of baseline data from five research trials, we conducted an exploratory factor analysis in one sample and validated the factor solution in a second sample. We then examined the relationship of the averaged subscales with tobacco outcomes and cigarette product features among current adult cigarette smokers (N = 752) who smoked ≥ 5 cigarettes daily for ≥ 5 years. ResultsThe results supported a three-factor solution: 1. Product harshness evaluation, 2. Smoking satisfaction, and 3. Positive sensory experience. Multivariable general linear models indicated that cigarettes per day was associated with a lower harshness rating b = −0.29 (95% CI: −0.51, −0.07) and higher positive sensory experience b = 0.32 (95% CI: 0.08, 0.56). FTND average dependence scores were associated with a more positive sensory experience b = 1.08 (95% CI: 0.28, 1.89). CO boost was associated with smoking satisfaction b = 0.77 (95% CI: 0.30, 1.26). ConclusionsThe Cigarette Ratings Scale subscales were primarily associated with behavioral outcomes, biological exposure, and nicotine dependence. This can help addiction efforts to determine how subjective evaluations of tobacco products relate to use behaviors.

Association of positive, negative, and disorganized schizotypy with cluster a, borderline, and avoidant personality disorders and traits.

The present study examined the associations of positive, negative, and disorganized schizotypy dimensions assessed by the Multidimensional Schizotypy Scale with 5 interview-rated personality disorder diagnoses and traits in 151 young adults. As hypothesized, all 3 schizotypy dimensions were associated with impaired functioning. Positive schizotypy was associated with schizotypal and borderline personality traits; negative schizotypy was associated with schizotypal, schizoid, paranoid, and avoidant personality traits; and disorganized schizotypy was associated with paranoid, borderline, and avoidant personality disorder traits. Negative schizotypy predicted broad diagnoses of Cluster A personality disorders. Both negative and disorganized schizotypy predicted the broad diagnosis of any of the 5 personality disorders. The study further examined the association of the schizotypy dimensions with the individual personality disorder criteria to better understand the overall associations. Given the common origins and high comorbidity, we examined whether the schizotypy dimensions explained the association of borderline and schizotypal personality disorder traits. Positive and disorganized schizotypy fully mediated the association between borderline and schizotypal traits. In summary, the study replicated and extended previous findings that the schizotypy dimensions are uniquely associated with personality disorders and traits, as well as impaired functioning, in young adults. The study also provided additional support for the construct validity of the Multidimensional Schizotypy Scale and for the use of psychometric assessment of schizotypy.

Development of Academic Writing Block Scale (AWBS): A Validity and Reliability Study

Academic writing block is a psychology-based writing problem that has a productivity-lowering effect on the publishing process. This study aimed to develop a valid and reliable assessment tool to measure academic writing block. To this end, during the pre-trial and trial applications, academicians were interviewed face to face. The main application was realized through the online form. A pre-reliability test, exploratory factor analysis (EFA) and total item correlation were conducted in the trial application. In the main application, reliability test, confirmatory factor analysis (CFA) and total item correlation were performed for construct validity. After the trial application, it was determined that the scale has a four-factor structure consisting of 23 items. Cronbach Alpha values were calculated to determine the preliminary reliability of the scale. CFA was conducted to test the construct validity of the Academic Writing Block Scale (AWBS). It was observed that the structure with four implicit variables determined in CFA was confirmed by the remaining 18 items in the scale. Besides, the total item correlation was used to test construct validity. Cronbach Alpha values were calculated to determine the reliability of AWBS. According to these values, it can be said that AWBS is a valid and reliable assessment instrument that can be used to measure academic writing block.

Validation and Assessment of a Tool to Measure Psychosocial Readiness to Use Modern Contraceptives among Women in Tigray, Ethiopia.

Social norms, beliefs, and attitudes around modern contraception (MC) use can influence the decision to take up a method, but susceptibility to these factors varies between individuals. The effect of psychosocial readiness to use MC at the individual level is not established for women in Ethiopia. Data from 349 women were used for validity and reliability testing of a 12-item MC psychosocial readiness scale. A rating-scale Rasch model tested for unidimensionality, rating scale functioning, and construct and content validity. Multiple linear regression assessed the effect of respondent characteristics on MC psychosocial readiness scores. The psychometric properties of the univariate MC psychosocial readiness scale were satisfactory after the stepwise removal of two items. Prior MC use, socioeconomic status, geographic zone, and education were significantly associated with increased endorsement of MC psychosocial readiness. The 10-item scale measures the extent of endorsement of MC psychosocial readiness for childbearing women in Tigray, Ethiopia. Further research should qualitatively explore the identified influence of education on MC psychosocial readiness.

Psychometric properties of the Turkish version of the Anxiety and Preoccupation about Sleep Questionnaire in clinical and non-clinical samples.

ObjectivesThe aim of the study was to investigate the psychometric properties of the Turkish version of Anxiety and preoccupation about sleep questionnaire (APSQ) in clinical and non-clinical samples.Material and MethodsTwo samples (141 university students and 42 patients with major depressive disorders) completed Turkish APSQ, the Pittsburgh sleep quality index (PSQI), the insomnia severity index (ISI) and the sociodemographic data form. Content validity analysis was performed with the Davis technique after the translation process of the original scale. Explanatory factor analysis and principal component analysis were performed to determine the scales construct validity, and internal consistency and temporal stability analyses were conducted to evaluate its reliability. The PSQI and the insomnia severity index (ISI) were used to assess criterion- related validity. In addition, we divided all the participants into two groups as good-sleepers and clinical insomnia according to ISI scores. Predictive validity analyses were also computed via comparing groups.ResultsConfirmatory factor analysis showed that the scale model aligns well with the original scales 10 items and two-factor structure. The scales and subdimensions Cronbach’s alpha coefficients were excellent (Factor 1; 0.935, factor 2; 0.906, total scale; 0.952). The test-retest correlations were 0.661 and 0.828 for depression group and university student group, respectively. Turkish APSQ scores were found to be significantly higher in both of the clinical groups (depression group vs. university student group, clinic insomnia group vs. good-sleepers group).ConclusionThe Turkish APSQ is adequate reliability and validity for assessing anxiety and preoccupation about sleep in Turkish clinical and non-clinical samples.

Validity and reliability of the spiritual care competency scale for oncology nurses in Taiwan

BackgroundNurses must have spiritual competence to provide holistic patient care. Therefore, the designed instrument to assess nurses’ competence could be a practical guide for health care professionals. This study aimed to evaluate the validity and reliability of the spiritual care competency scale (SCCS) for oncology nurses in Taiwan.MethodsThis study used a convenience sample from a regional teaching hospital in Taiwan from November 2017 to February 2019, who were asked to complete the SCCS. We employed scale-content validity index (S-CVI). Exploratory Factor Analysis (EFA) was also used to evaluate the structural factor of SCCS. Confirmatory Factor Analysis (CFA) verified the construct validity of SCCS scale for oncology nurses in Taiwan. Test–retest reliability were also measured in this study at 2-week interval.ResultsThe average S-CVI of SCCS was 0.96. The EFA produced four factors of 27 items, such as professionalization, improving the quality of spiritual care, personal support, patient counseling and referral, attitude towards patient spirituality and communication, assessment, implementation providing and evaluation of spiritual care. Fitting the 27 items yielded an acceptable model fit; X2/df = 2.41, RMSEA = 0.08, GFI = 0.80, AGFI = 0.80, CFI = 0.92, IFI = 0.92, NFI = 0.90, RFI = 0.90, TLI = 0.91, SRMR = 0.06. Cronbach’s alpha values were between 0.93 and 0.95, and the total Cronbach’s alpha was 0.96. The intraclass correlation coefficient (ICC) scores were between 0.43 and 0.88.ConclusionsThe result of this study demonstrated satisfactory validity and reliability for the SCCS in the nursing field in Taiwan. Implications for practice in this study serves as a reference for effectively evaluating nursing competency in spiritual care.

End-Users Satisfaction with Positive Deviance Approach as an Intervention to Promote Exclusive Breastfeeding in Jimma, Ethiopia: A Multi-Level Analysis.

BackgroundPositive deviance approach (PDA) was implemented as an intervention strategy to address the poor practice of exclusive breastfeeding (EBF) in Jimma town, Ethiopia. Understanding the end-users satisfaction and its drivers is essential to determine whether this approach will be viable in the long run. Therefore, we determined the level of users’ satisfaction with the intervention and identified multi-level predictors to explain variability.MethodsThe data for this follow-up study were collected from September 01 to 25, 2020 among the study participants who were living in the intervention clusters of an earlier trial. A sample of 260 participants were invited to respond to an interviewer-administered structured questionnaire that assessed both individual and community-level variables. The developed tool was refined using experts’ view (face validity) and using factor analysis (FA) to validate the satisfaction measurement scales (construct validity). The mean scores were standardized using Percentages Scale Mean Score (PSMS) formulae. Two-level mixed-effects linear regression (linear mixed models) were performed to fit individual, community, and mixed-level variables. All assumptions were checked for each analysis as appropriate and β-estimates at 95% CI and p-value of <0.05 were considered to declare a level of significance.ResultsThe overall level of end-users’ satisfaction (PSMS) with PDA as an intervention to improve EBF was 50.9% with a maximum score of 99% and a minimum of 8%. Of the emerged satisfaction measuring scales, the standardized mean score for the user empowerment scale was the highest (53.7%). Five scales were emerged with 84.2% of the total variability explained in users’ satisfaction. The mixed-effect model revealed that age, occupation, experience of breastfeeding (BF), knowledge, attitude, self-efficacy, main source of BF information, previous home visit/support received from HEPs, participation in any social activities, and perceived community support for BF were independent two-level predictors of satisfaction.ConclusionAs an intermediate outcome, more than half of the end-users of the PDA intervention were satisfied. End-users’ satisfaction with PDA as an intervention to promote EBF was predicted by multi-level factors. If they chose to use PDA as an intervention, Health program managers should be mindful of the two-level factors identified in this study.

Adaptation of appearance-related social media consciousness scale into Turkish: A validity and reliability study on adolescents

(2020), into Turkish and carry out validity, reliability, and standard-setting studies on adolescents. The study was conducted on 444 adolescents, 296 of whom were girls. Confirmatory factor analysis was used to determine the scale's construct validity. Correlation analysis was performed for criterion validity, and Cronbach alpha and composite reliability coefficients were calculated for reliability. Confirmatory factor analysis results showed that the scale fits perfectly. The scale showed a moderate positive correlation with social appearance anxiety, depression, anxiety, and stress. In addition, the reliability coefficients were over .90. The results indicated that ASMC has good psychometric properties.

EXPLORATORY STRUCTURAL EQUATION MODELING IN SECOND LANGUAGE RESEARCH

AbstractThis study offers methodological synergy in the examination of factorial structure in second language (L2) research. It illustrates the effectiveness and flexibility of the recently developed exploratory structural equation modeling (ESEM) method, which integrates the advantages of exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) into one complete measurement model. Two sets of data were collected using the L2 Passion Scale, which measures a dualistic model of passion. Study 1 participants were 220 L2 students. A comparison was made between the CFA and the ESEM models. The results demonstrated the superiority of the ESEM method relative to CFA in terms of better goodness-of-fit indices and realistic correlated factors. These results were replicated in another sample of 272 L2 students, providing support for the predictive validity using a structural ESEM model. Guidelines are provided and Mplus syntax files (codes) are included to help analysts apply the methods. We also make the data available publicly. Overall, this research demonstrated the usefulness of ESEM for examining the construct, discriminant, and convergent validity of L2 scales over CFA.
