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…

Previous work has focused on positive feelings of mattering, which pertain to the human need to feel significant. In the current article, we examine a complementary yet distinct construct involving feelings of not mattering that may arise from being marginalized and experiences that heighten a sense of being insignificant to others. We also…

This study proposes a revision (R) of the Center for Epidemiologic Studies Depression Scale for youth with ID (CESD-ID) in English and French. 346 youth (36.02% girls) with mild (51.26%) and moderate (48.78%) ID (11-22 years; M = 15.69), enrolled in secondary schools in Canada (French-speaking; n = 115), and Australia (English-speaking; n = 231),…

Little is known about the specific manner in which students cope with academic failure. To address this gap, a new measure of failure-coping behaviour was developed and validated. Two hundred and thirty-eight undergraduate students completed a new measure of failure-coping behaviour, in addition to measures of failure appraisal, depressed mood,…

Background: The purpose of this study was to develop and validate a short form of the "Perceived Stress Questionnaire" (PSQ) in people with spinal cord injury (SCI). Methods: The sample consisted of 274 individuals with SCI. Measures administered were the "PSQ-20, Center for Epidemiological Studies-Depression Scale," and…

Despite the availability of effective early interventions, few toddlers with emotional and behavioral issues receive these services. This situation exists partly due to challenges in the identification of mental health issues in young children. We developed the Brief Child and Family Intake and Outcomes System for toddlers, which is a 36-item…

Objective: We assessed the validity of the Center for Epidemiological Studies Depression Scale for Children (CES-DC) as a screen for depression in Rwandan children and adolescents. Although the CES-DC is widely used for depression screening in high-income countries, its validity in low-income and culturally diverse settings, including sub-Saharan…

There is a need to identify children with potential mental health issues early in order to provide "an ounce of prevention." Unfortunately, there are few instruments available to identify emotional and behavioral issues in infants and many never receive intervention. We developed the Brief Child and Family Intake and Outcomes System for…

This study investigated the psychometric properties of the Iranian translation of the Centre for Epidemiological Studies Depression Scale for Children (CES-DC) in school children and adolescents in Iran. The CES-DC is a 20-item self-report scale designed to measure depressive symptoms in children and adolescents. A total of 1,984 children and…

Five studies document the validity of a new 8-item scale designed to measure "positivity," defined as the tendency to view life and experiences with a positive outlook. In the first study (N = 372), the psychometric properties of Positivity Scale (P Scale) were examined in accordance with classical test theory using a large number of…

Using two clinical samples of patients, the presented studies examined the construct validity of the recently revised Anxiety Sensitivity Index-3 (ASI-3). Confirmatory factor analyses established a clear three-factor structure that corresponds to the postulated subdivision of the construct into correlated somatic, social, and cognitive components.…

This study examines whether students perceive three different types of fit in an academic environment (i.e., interest-major [I-M] fit, demands-abilities [D-A] fit, and needs-supplies [N-S] fit) and whether these factors predict important academic and well-being criteria using a Chinese student sample. Results from confirmatory factor analyses…

Psychometric properties of the Almost Perfect Scale and the Family Almost Perfect Scale were evaluated using Indian college students studying in India (N = 132). Three classes of perfectionists--adaptive, maladaptive, and nonperfectionists--that mirrored past studies were compared on self-esteem and depression. (Contains 3 tables and 3 figures.)

This article describes the development and validation of the Multidimensional State Boredom Scale (MSBS)--the first and only full-scale measure of state boredom. It was developed based on a theoretically and empirically grounded definition of boredom. A five-factor structure of the scale (Disengagement, High Arousal, Low Arousal, Inattention, and…

This study investigated the Consequences of Perfectionism Scale (COPS) and its relationships with perfectionism, performance perfectionism, affect, and depressive symptoms in 202 university students using confirmatory factor analysis, correlations, and regression analyses. Results suggest that the COPS is a reliable and valid measure of positive…
