Problem
I. Study: Effects of a coping-oriented supportive programme for people with spinal cord injury during inpatient rehabilitation: A quasi-experimental study (Li et al., 2020).
II. Statement of Purpose: The purpose of the study was to evaluate the effectiveness of a coping-oriented supportive program in improving people's psychosocial outcomes following a spinal cord injury. It was hypothesized that participation in the program would contribute to greater improvement in coping ability and self-efficacy.
III. Treatment Groups: The program was a psychosocial intervention for people with spinal cord injury (SCI) undergoing inpatient rehabilitation. The program consisted of eight weekly group sessions lasting 1 to 1.5 hours that provided guidance on problem solving, adaptive coping, and communication skills. The program was delivered by registered nurses in two similar rehabilitation hospitals. One ward in each hospital was selected, at random, to receive the intervention. Patients from two different wards in the same hospitals received an attention control treatment involving eight brief educational sessions (e.g., self-care information, bowel and bladder training).
IV. Method: To estimate their sample size needs, the researchers undertook a power analysis (see Chapter 9) that suggested that a sample of 50 patients per group would be needed to achieve statistical conclusion validity. A total of 99 patients (50 in the intervention group and 49 in the comparison group) participated in the research. Patient-reported assessment data for the primary outcomes and several secondary outcomes (e.g., anxiety, depression) were gathered at baseline, immediately after the intervention, and at two follow-ups. At the final 12-week follow-up, data were collected from 43 patients in the intervention group and 41 patients in the control group.
V. Key Findings: The intervention and comparison group members were similar demographically and clinically on most baseline traits, but people in the comparison group were less likely to be married and less likely to use analgesic or psychotropic medication than those in the intervention group. The analysis of program effects revealed statistically significant improvements for those in the intervention group, compared to those in the comparison group, with respect to coping, self-efficacy, depression, anxiety, and life satisfaction.
• Was the design experimental, quasi-experimental, or nonexperimental? What specific design was used? Was this a cause-probing study? Given the type of question (Therapy, Prognosis, etc.), was the most rigorous possible design used?
