Person perception and the type A coronary-prone behavior pattern

Comparing five alternative factor-models of the Student Jenkins Activity Survey: separating the wheat from the chaff

The Student Jenkins Activity Survey (SJAS; Glass, 1977) is the most popular instrument for measuring Type A behavior in college undergraduates, and a variety of different unidimensional and multidimensional models for scoring the SJAS have been employed in the past. This study compared five alternative factor-models developed for the short (21-item) form of the SJAS in terms of their overall goodness of fit, factorial invariance, and factor reliabilities, using the data of two independent samples of undergraduates. Indices of relative fit for the five models ranged from .64 to .94 (median = .85), but only one unidimensional model and one multidimensional model achieved a minimum satisfactory goodness of fit (.90 or greater) for both samples. Reconceptualizing these models within a broader nomological net sheds light on their meaning and highlights existing gaps in the measurement of multifaceted Type A behavior.

The A type behaviour pattern, mental health and health locus of control beliefs

Despite the fact that a considerable amount of research has considered the relationship between A type behaviours and specific aspects of physical health few studies have looked at the relationship between A type behaviours, mental health and health beliefs. This study set out to determine the relationship between type A behaviours, psychological disturbance and various health locus of control beliefs in a heterogeneous population. It was hypothesized that although A type individuals would have higher disturbance scores, they would have higher internal locus of control beliefs across all subscale scores. The results showed that A type individuals had significantly higher mental distress scores than B types, however there was no relationship between health locus of control beliefs and the A type behaviour pattern. The findings are discussed in terms of the coping strategies of the A type individual.
