School attendance problems (SAPs) become manifest in many ways and are associated with multiple risk factors, calling for comprehensive assessment methods. This study documents the development of the inventory of school attendance problems (ISAP), which assesses both the quality and the function of a broad spectrum of SAPs by first asking students with SAPs to rate the intensity of symptoms prior to or at school and then to rate their impact on school attendance. An empirically generated pool of 124 items was analyzed (explorative factor analysis) using a clinical sample of N = 245 students with SAPs (53.5% male; M: 14.4). The Youth Self Report (YSR), a German version of the School Refusal Assessment Scale (SRAS), and the extent of school absenteeism were used to determine construct validity. The resulting 48 items loaded on 13 factors. The 13 scales assess internalizing and externalizing symptoms (Depression, Social Anxiety, Performance Anxiety, Agoraphobia/Panic, Separation Anxiety, Somatic Complaints, Aggression, School Aversion/Attractive Alternatives) as well as emotional distress due to problems in the school or family context (Problems with Teachers, Dislike of the Specific School, Problems with Peers, Problems Within the Family, Problems with Parents). All scales showed good internal consistencies. Their correlations with the YSR and the SRAS indicated convergent and discriminant validity. Positive associations between most of the scales and the extent of school absenteeism were obtained. Although preliminary, these results support the usefulness of the ISAP for a comprehensive assessment of SAPs in clinical settings.
Many preventive and therapeutic interventions are now available, but the existing measures need to be better coordinated, and more effort needs to be directed to the early recognition and treatment of school-avoiding behavior. Physicians should consider the possibility of mental illness. Rather than writing sick notes or prescribing mother-child treatments at health resorts, which rather tend to sustain the problem, they should refer patients promptly to a child and adolescent psychiatrist.
Objective measurements of ADHD symptom levels can be a highly valuable complement to ratings. However, sometimes it is not feasible to bring patients into the clinic/lab for assessment. The aim of the present study was therefore to evaluate the psychometric properties of the QbCheck, an online computerized test that measures errors and reaction time as well as activity during testing using the computer's built‐in web camera. Study I (n = 27 adolescents/adults) investigated test–retest reliability and concurrent validity of the QbCheck. Study II included 142 adolescents/adults (69 with ADHD/73 controls) and investigated convergent and diagnostic validity, as well as usability, of the QbCheck. In Study I, the QbCheck showed high test–retest reliability and high concurrent validity. In Study II, high convergent validity was observed when studying associations between the QbCheck performed in the home and the QbTest performed at the clinic. In addition, the QbCheck discriminated well between patients with ADHD and controls, with a sensitivity of 82.6 and a specificity of 79.5. The QbCheck appears to be a valuable test with good psychometric properties and will thereby enable assessment of ADHD symptom levels in adolescents and adults outside the clinic in the home setting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
