[Development of a scale for work motivation of home care workers and influencing factors].
OBJECTIVE
To develop a scale for home care workers focusing on work motivation and to determine influential underlying factors.


METHODS
This study was an anonymous mailed survey of home care workers who provided home help services in July 2007. We collected information in the following areas: demographics of home care workers and care-recipients, burnout, stress, job satisfaction, life satisfaction, and self-esteem (SE). Hierarchical regression analysis was performed in order to identify factors related to work motivation.


RESULTS
Construct validity was analyzed by factor analysis. Two subscales were obtained by the analysis and designated as "positive appraisal of the current state" (9 items) and "uplift of morale" (3 items). Content validity was analyzed by good-poor and item-total, and all correlations were strongly positive. Reliability was analyzed by internal consistency. Cronbach's ? values were 0.94 and 0.77, respectively. Concurrent validity was analyzed by correlation coefficient and a significant negative correlation was seen between the two subscales and burnout (r = -0.23--0.50), while positive correlations were noted for job or life satisfaction (r= 0.24-0.49). The positive influential factors on "positive appraisal of the current state" were satisfaction in 1) relation to care-recipients, 2) work environment for skill improvement and 3) the wages. The positive influential factors on "uplift of morale" were satisfaction with relation to care-recipients and their own life.


CONCLUSIONS
This scale has sufficient reliability and validity. "Positive appraisal of the current state" and "uplift of morale" were confirmed as appropriate work motivation subscales for home care workers. Thus, support to augment job satisfaction with the work environment and wages appears to enhance "positive appraisal of the current state" and support to augment life satisfaction appears to enhance "uplift of morale".
