OBJECTIVE: To synthesize current knowledge of the modifiable psychosocial
constructs associated with physical activity (PA) participation in people with
multiple sclerosis. DATA SOURCES: A search was conducted through October 2015 in 8 electronic databases: CINAHL, PubMed, SPORTDiscus, Web of Knowledge, MEDLINE,
EMBASE, Cochrane Database of Systematic Reviews, and PsycINFO. STUDY SELECTION:
Cohort and intervention studies were included if they (1) included an objective
or subjective measure of PA; (2) measured at least 1 modifiable psychosocial
construct; and (3) reported bivariate correlations (or these could be extracted)
between the PA and psychosocial construct measures. A total of 13,867 articles
were screened for inclusion, and 26 were included in the final analysis. DATA
EXTRACTION: Meta-analyses of correlations were conducted using the Hedges-Olkin
method. Where a meta-analysis was not possible, results were reported
descriptively. DATA SYNTHESIS: Meta-analyses indicated a pooled correlation
coefficient between (1) objective PA and self-efficacy (n=7) of r=.30 (P<.0001),
indicating a moderate, positive association; (2) subjective PA and self-efficacy
(n=7) of r=.34 (P<.0001), indicating a moderate, positive association; (3)
subjective PA and goal-setting (n=5) of r=.44 (P<.0001), indicating a
moderate-to-large positive association; and 4) subjective PA and outcome
expectancies (n=4) (physical: r=.13, P=.11; social: r=.19, P<.0001;
self-evaluative: r=.27, P<.0001), indicating small-moderate positive
associations. Other constructs such as measures of health beliefs, enjoyment,
social support, and perceived benefits and barriers were reported to be
significantly correlated with PA in individual studies, but the number of studies
was not sufficient for a meta-analysis. CONCLUSIONS: Future PA interventions
should continue to focus on the psychosocial constructs of self-efficacy and
goal-setting. However, there is a need to explore the associations between other
constructs outside those reported in this review.
