Translation and validation of the Chinese powerlessness assessment tool

Abstract

The objectives of this study were to translate the powerlessness assessment tool (PAT) into Chinese, and to evaluate its psychometric performance. The PAT was translated into Chinese and was evaluated in patients with chronic wounds. Mean PAT scores were compared between various wound types to evaluate the scale's power to differentiate wound severity (PUSH score). There were 154 consecutive patients included in this study. All items were included, and the results of item-domain correlation (r ranged from 0.838 to 0.967) and small-group analysis (critical ratio, p < 0.05) were satisfactory. Furthermore, the Chinese PAT also showed good criterion validity when correlated with the Cardiff wound impact schedule (r = 0.726, p < 0.01). Exploratory factor analysis of these items extracted only two domains instead of the hypothesized three domains: self-perception of behavioral control and decision making (9 items) and emotional responses to perceived control (3 items), explained 82.045% of the variance. Sensitivity was demonstrated between patients with different activity of daily living, wound severity (PUSH score) and wound types. The internal consistency of all scales of the Chinese PAT was consistently high (Cronbach's alpha ranged from 0.939 to 0. 965) and split-half reliability was 0.901. In conclusion, the validated Chinese PAT has good psychometric properties, and may be used to objectively evaluate the powerlessness experience of Chinese patients with chronic wounds.

Quality of Life and Its Influencing Factors in Chinese Patients with Chronic Wounds

“…The lowest average score of all domains was on well-being. This finding parallels the results of several other studies; 23,26,27 however, Lozano-Platonoff et al 28 found that the lowest CWIS domain score was for social life. Studies on the QoL of patients with chronic wounds help researchers gain a better understanding of the challenges that patients face and the adaptive strategies they use, as well as the factors that relate to QoL among these patients.…”

The Mediating Role of Self-efficacy and Coping Mode Between Powerlessness and Quality of Life in Patients with Venous Leg Ulcers

“…The scale has good reliability and validity, with an overall Cronbach α of .96, meaning it is suitable for use with Chinese patients with chronic wounds. 22 The Cronbach α in the present research was .862.…”

“…Each item was scored from to 1 (never) to 5 (always), with higher scores corresponding to stronger feelings of powerlessness. The scale has good reliability and validity, with an overall Cronbach α of .96, meaning it is suitable for use with Chinese patients with chronic wounds 22 . The Cronbach α in the present research was .862.…”

“…The Chinese version of the Powerlessness Assessment Tool was used to assess the level of powerlessness among patients with VLUs. 22 The scale includes 12 items and two dimensions. Each item was scored from to 1 (never) to 5 (always), with higher scores corresponding to stronger feelings of powerlessness.…”
