Abstract

Background:
Life tasks are the pillars of daily private life that underlie personal well-being and health. Bakker et al. (2019) developed the Life Tasks Test (LTT) to assess the perceived effectiveness in life task functioning and found evidence for its psychometric properties (e.g., factorial structure and criterion validity) in a rescue worker sample.

Aims:
This paper aims (1) to verify Bakker et al.’s (2019) findings by replicating the study design and (2) assessing the generalisability to an office worker sample.

Method:
Cross-sectional data on rescue workers (n = 412) and office workers (n = 726) were used to confirm reliability, convergent validity, factorial structure, and criterion validity of the LTT.

Results:
The reliability estimates are shown to be acceptable in both samples. The hypothesised factor structure is shown to have adequate fit on the data, after adjustment of the initial 20-item model. Perceived life tasks functioning accounted for substantial variance (r = ~.30) in negative affect. In rescue workers significant differences in life tasks scores were found for gender- and age-based subgroups. In office workers, significant differences were substantiated according to occupation.

Limitations:
The sample of rescue workers wholly consists of police officers and, therefore, represents only part of the rescue worker population. Furthermore, it is yet to be shown if the results are replicable for healthy populations.

Conclusions:
The present findings confirm that most of Bakker et al.’s (2019) original findings are replicable in a new clinical sample of rescue workers and generalisable to a clinical sample of office workers. This study contributes to the growing body of research on positive health self-management and its measurement.
