Psychometric Evaluation of Brief Reason for Living Inventory for Adolescents (BRFL-A) Instrument in the Indonesian Language.

Objectives. The Brief Reason for Living Inventory for Adolescents (BRFL-A) is used to assess protective factors against suicide in non-clinical settings. This study aimed to validate the psychometric properties of BRFL-A in Bahasa Indonesia. Methods. A total of 728 high-school and university students filled BRFL-A questionnaire and the results were analyzed. The reliability, content, convergent, discriminant, and factorial or construct validity, were investigated using content validity index Cronbach's Alpha, while content validity index (CVI), confirmatory factor analysis, and Pearson product-moment correlation were assesed with MSPSS, SIS, INQ-15, and DASS-18. Results. The results showed that the Indonesian version of BRFL-A had good internal consistency, test-retest reliability, as well as content and concurrent validity, supporting both the 1-factor and the 5-factor model of factorial validity. Conclusions. The Indonesian version of the BRFL-A was valid and reliable to measure protective factors against suicide risk among adolescents and young adults in non-clinical settings.

Validity and reliability of the Difficulties in Emotion Regulation Scale Short Form in Indonesian non-clinical population.

Introduction: Emotion dysregulation is a transdiagnostic marker for vulnerability and has high comorbidity rates across various range of disorders among adolescents and young adults, highlighting the crucial need for precise assessment tools to recognize its significant impact on well-being. The Difficulties in Emotion Regulation Scale Short Form (DERS-SF) is a comprehensive instrument designed to measure the ability to regulate emotion. This study aimed to investigate the psychometric properties of DERS-SF among the non-clinical population, particularly high school and university students in Indonesia. Methods: A total of 738 senior high school and university students completed the Indonesian version of DERS-SF and standard questionnaires to assess its validity, consisting of the Depression Anxiety Stress Scale (DASS), the Beck Depression Inventory-II (BDI-II) for young adults and the Children Depression Inventory (CDI) for adolescents. Three models were examined in factorial validity tests using confirmatory factor analysis. Results: The results showed that DERS-SF had an overall good internal consistency with Cronbach's alpha coefficient of.89 for the 18-item version,.90 for the 17-item version, and.91 for the 15-item version. Test-retest reliability was moderate with a value of.67. In addition, it had good satisfactory content as shown by item content validity index (I-CVI) = .96 and scale content validity index (S-CVI) = .83, as well as convergent validity. All subscales scores showed a positive and strong correlation with DASS, BDI-II, and CDI except awareness. Based on confirmatory factor analysis (CFA), the correlated 6-factor model excluding item number 6, and the 5-factor model excluding awareness were suitable to use in non-clinical populations. Conclusion: This study established the removal of the awareness subscale in the DERS-SF Indonesian version, resulting in better reliability and validity than the original version with complete subscales.

Psychometric Properties of the Suicidal Ideation Scale in the Indonesian Language.

INTRODUCTION: Suicide is one of the leading cause of mortality among adolescents and young adults, especially in low to middle-income countries. Research found that screening for suicidal ideation in non-clinical populations such as schools or communities is an important step toward preventing suicide. Despite so, not all screening tools have the capabilities to accurately detect suicidal ideation among adolescents and young adults in non-clinical populations. The Suicidal Ideation Scale (SIS) is one of the most used questionnaires to measure suicidal thoughts in non-clinical populations. This study aims to investigate the psychometric properties of SIS among adolescents and young adults in Indonesia, especially in non-clinical populations. METHODS: After a series of language and cultural adaptations, 1254 senior high school and university students completed the Indonesian version of SIS using 3 standard questionnaires, namely Patient Health Questionnaire-9/PHQ-9, Beck Depression Inventory-II/BDI-II, and Children's Depression Inventory/CDI. The SIS content validity, internal consistency, test-retest reliability and concurrent, as well as internal structure validity, were investigated using content validity index (CVI), Cronbach's Alpha, Pearson product-moment correlation, and confirmatory factor analysis (CFA), respectively. RESULTS: The result showed that SIS has good to excellent internal consistency and test-retest reliability. Based on the validity indicators, it has satisfactory content and convergent validity, and further support the one-factor and 2-factor model for factorial validity. Both one-factor and 2 factor model are suitable to use in non-clinical settings. CONCLUSIONS: SIS is a valid and reliable tool for suicide ideation screening in adolescents and young adults in non-clinical populations. This validated questionnaire can be used in the early detection of suicidal ideation among adolescents and young adults in non-clinical populations, thus contributing to developing strategies and policies to prevent suicide among Indonesian adolescents and young adults at group and institutional levels.

Psychometric evaluation of the interpersonal needs questionnaire in the Indonesian language.

Suicide remains one of the leading causes of death among youths and the commonly reported associated risk factor is interpersonal needs, which consists of perceived burdensomeness and thwarted belongingness. To date, there is no validated interpersonal needs questionnaire in Indonesia. Therefore, this research aims to validate and evaluate the psychometric properties of the Interpersonal Needs Questionnaire (INQ-15) among adolescents and young adults in the Indonesian language. Based on the results, the INQ-15 has high internal consistency and test-retest reliability. It was also found to have satisfactory content and concurrent validity, as well as support two factor model of factorial validity. This implies that The Indonesian version of the INQ-15 is a valid and reliable questionnaire to measure the interpersonal needs among adolescents and young adults, both in clinical and research applications.
