The Perceptions of Inclusion Questionnaire (PIQ) assesses the perceptions of inclusion in 3rd to 9th grade students through three scales: social inclusion, emotional inclusion, and academic self-concept. This study aimed to establish the psychometric properties of the Spanish version of the instrument (PIQ-Spa) since no prior formal validation of…

The Forms of Bullying Scale was introduced in 2013 and was normed with a large group of Australian students aged 12 to 15 (Shaw et al., 2013). To date, no researchers have attempted to validate FBS on adolescents in the United States. The purpose of this paper is to provide validation for the Forms of Bullying Scale -- Perpetration (FBS-P; Shaw et…

Introduction: There are numerous instruments for the measurement of gender awareness. However, there are relatively few validated instruments with a broad overarching holistic vision of gender that do not approach the issue from an adult perspective. For this reason, this study puts forward validated scale for measurement of Gender Awareness…

This study aimed to evaluate the psychometric properties and gather evidence supporting the validity of scores from a traditional Chinese version of the Claremont Purpose Scale (TC-CPS) among Taiwanese adolescents. The TC-CPS, measuring meaningfulness, goal directedness, and beyond-the-self orientation, was administered to 233 high school and 445…

Objective: Cyberbullying, which is defined as an intentional, aggressive, and repetitive behaviour where a person or group uses electronic devices (primarily the Internet and smartphones), is a new concept specifically for the Iranian educational system. We examined the Bullying and Cyberbullying Scale for Adolescents' (BCS-A) psychometric…

Background: Studies that have systematically reviewed the psychometric properties of health-related quality of life (HRQoL) and subjective wellbeing instruments for adolescents with intellectual disabilities narrowly focus on disease or health-specific conditions. This review aimed to critically appraise the psychometric properties of self-report…

Background: The Social Emotional Distress Scale-Secondary (SEDS-S) is a short measure designed for comprehensive school-based mental health screening, particularly for using very brief self-reported measures of well-being and distress. Whereas prior studies have shown validity and reliability evidence for the English version, there is a lack of…

This dissertation presents an innovative approach to examining the keying method, wording method, and construct validity on psychometric instruments. By employing a mixed methods explanatory sequential design, the effects of keying and wording in two psychometric assessments were examined and validated. Those two self-report psychometric…

Adolescent anhedonia is a multidimensional construct defined as the loss of enjoyment or pleasure across multiple domains of life. Anhedonia is concurrently associated with substantial impairment and distress, and it prospectively predicts the onset, severity, and treatment of depression. Despite its demonstrated importance, a limited number of…

Internalizing and externalizing problems are common targets for school mental health screening. Prior research supports the interpretation of scores from the Youth Internalizing Problems Screener (YIPS) and the Youth Externalizing Problems Screener (YEPS), which were developed separately yet intended as companion measures. We extended previous…

The present study aims to develop the Cyberbullying Awareness Scale (CAS) for adolescents, which assesses adolescents' awareness about cyberbullying, and to examine the psychometric properties of the scale by conducting validity and reliability studies. In this context, evidence on the validity and reliability of the scale was obtained in two…

Objective: The original 24-item School Refusal Assessment Scale-Revised (SRAS-R) assesses four functions/conditions regarding school refusal behavior (SRB), bridging assessments, and treatments of SRB. No validated Chinese versions are available. Methods: To validate the Chinese version of the SRAS-R, an anonymous cross-sectional survey was…

Objective: We aimed to examine the psychometric properties of the Scale of Perfectionism and Excellencism (SCOPE) in a novel sample, Australian adolescents. Method: The cross-sectional sample consisted of 350 participants (79 male, 271 female; mean age 17.9 years, age range = 15-20 years) from a secondary 10 school and university who completed a…

Perceived parenting is a crucial and complex factor for the psychological well-being of adolescents. The Adolescent Family Process Short-Form (AFP-SF) investigates the perception of adolescents' maternal and paternal parenting across six dimensions: closeness, support, communication, monitoring, peer approval, and conflict. This was the first…

The Behavioral Inflexibility Scale (BIS) is a recently developed measure of behavioral inflexibility, defined as rigid patterns of behavior that contrast with the need to be flexible when the situation calls for it. In this study, we sought to replicate previous findings on the psychometric properties of the BIS in a community sample. Data for…
