Table 3.

Standardized perceived benefit and barrier sub-scale means and standard deviations and t-test values for multiple comparisons.

Sub-scale	Mean (SD)	Sub-scale^†
Sub-scale	Mean (SD)	1	2	3	4	5
Benefits (M = 2.96, SD = 0.44)

1. Physical performance	3.25 (0.46)	- -	6.36^*	5.80^*	11.80^*	17.93^*
2. Psychological outlook	3.08 (0.60)		- -	0.72	5.36^*	14.22^*
3. Preventive health	3.05 (0.56)			- -	3.57^*	10.83^*
4. Life enhancement	2.93 (0.48)				- -	11.97^*
5. Social interaction	2.50 (0.65)					- -

Barriers (M = 2.22, SD = 0.46)

1. Physical exertion	2.63 (0.60)	- -	11.37^*	12.72^*	10.27^*
2. Time expenditure	2.12 (0.59)		- -	1.39	1.35
3. Exercise milieu	2.08 (0.60)			- -	0.39
4. Family discouragement	2.06 (0.62)				- -

For all subscales, possible scores range from 1 to 4, where 4 represents the highest perception of both benefits and barriers;

^†

Values in the cells of these columns are actual t-test values;

Indicates that the means of the subscales that are being compared were significantly different, using Bonferroni corrected critical p values for benefits (p < 0.005) and for barriers (p < 0.008).
