Intervening to reduce workplace sitting: mediating role of social-cognitive constructs during a cluster randomised controlled trial

Table 3 Relationships between concurrent changes in social-cognitive constructs with changes in workplace sitting time at 3 and 12 months (Path B)

	Workplace sitting time change		Workplace sitting time change
	Baseline to 3 months^a		Baseline to 12 months
	b (95% CI)^c	p	b (95% CI)^c	p
Perceived behavioural control	−12.74 (−27.08, 1.61)	0.082	−0.44 (−19.72, 18.84)^b	0.964
Barrier self-efficacy	−5.63 (−16.10, 4.85)	0.292	−19.17 (−32.45, −5.90)^c	0.005
Perceived organisational norms	−5.20 (−24.70, 14.29)	0.601	−0.20 (−23.08, 22.67)^c	0.986
Knowledge	−11.92 (−27.95, 4.11)	0.145	−13.62 (−33.83, 6.58)^b	0.186

Note: For each construct, minimum score = 1 and maximum score = 5. Significant effects are indicated in bold.
Models adjusted for intervention status and baseline values of the following potential confounders: workplace sitting (min/8 h), age (years), gender (men/women), Caucasian ethnicity (yes/no), current smoking (yes/no), body mass index (log-transformed), AQoL-8D physical superdomain score (log-transformed), AQoL-8D mental superdomain score (log-transformed), TV viewing time (log-transformed), job control category (high/low), weekly headaches (yes/no), musculoskeletal symptoms in the upper extremities (none/does not interfere with activities/interferes with activities)
^a n = 186; ^b n = 146 ^c n = 145
