Problem Gambling in Adolescents: An Examination of the Pathways Model

This research tests the applicability of the Integrated Pathways Model for gambling to adolescent problem gamblers, utilizing a cross-sectional design and self-report questionnaires. Although the overall sample consisted of 1,133 adolescents (Quebec: n = 994, 87.7 %; Ontario: n = 139, 12.3 %: Male = 558, 49.5 %; Female = 569, 50.5 %), only problem gamblers were retained in testing the model (N = 109). Personality and clinical features were assessed using the Millon Adolescent Clinical Inventory, attention deficit hyperactivity (ADHD) using the Conners–Wells’ Adolescent Self-Report Scale, and the DSM-IV-MR-J and Gambling Activities Questionnaire to determine gambling severity and reasons for gambling. Latent class analysis concluded 5 classes, yet still provided preliminary support for three distinct subgroups similar to those proposed by the Pathways Model, adding a depression only subtype, and a subtype of problem gamblers experiencing both internalizing and externalizing disorders. ADHD symptoms were found to be common to 4 of the 5 classes.

Boredom in the workplace: More than monotonous tasks

Boredom is an emotional state that has a long history in organizational research. Despite recent changes in technology and the organization of work, boredom remains a part of the experience of work. The available evidence indicates that boredom is associated mainly with negative individual and organizational outcomes. The authors organize the review of the antecedents of boredom around four major themes in the literature: boredom in relation to jobs; individual differences; social context; and goals and coping. The authors conclude that the major challenge for researchers is to provide an integrative account of boredom which subsumes multiple areas of research, and that one most promising avenue for future research requires further attention to boredom in relation to coping processes, pursuit and attainment of personal goals.
