The study was conducted in 2013 by following a pretest-posttest controlled quasi-experimental design. The study population was the residents of the nursing homes located in Urmia, Iran. All 60 eligible elderly people were conveniently recruited. They were included if they were 60 years old or more (
1), oriented to time, place and person, did not receive psychotherapy or experience the loss of close relatives during the last six months before the study, did not receive treatments which could affect mental abilities, memory, or thinking, and did not have hearing or speech impairment, debilitating conditions, and physical disorders which could affect mental health (such as thyroid disorders). On the other hand, those participants who experienced any significant negative event or death were excluded from the study. After obtaining a written informed consent from the subjects, they were randomly allocated to an experimental or a control group using randomization software.
A demographic questionnaire and the Persian version of the short-form 36-item QOL questionnaire (SF-36) were employed for data collection (
11). The questionnaires were completed for the participants through the interview technique. The SF-36 is a valid and reliable questionnaire which contains 36 questions and assesses QOL in eight domains including physical functioning, role performance, bodily pain, general health perception, vitality, social functioning, emotional functioning and mental health. Three-, five- and six-choice questions of the SF-36 are scored on three-, five-, and six-point scales of ‘0, 50 and 100’, ‘0, 25, 50, 75, and 100’, and ‘0, 20, 40, 60, 80, and 100’, respectively. Therefore, the total score of each domain ranges from 0 to 100, the higher the score the better the QOL. The validity and the reliability of the SF-36 were evaluated in different studies. For example, Heidari and Shahbazi found that the Cronbach’s alpha and the test-retest correlation coefficient of the survey were 0.83 and 0.87, respectively (
16). Hamidizadeh et al. also confirmed the content validity of the SF-36 and reported a test-retest correlation coefficient of 0.87 (
17). Montazeri et al. also noted that the SF-36 had an acceptable validity and reliability (
18).
To design the study intervention, authors initially assessed and identified each participant’s physiological, self-concept, role function and interdependence maladaptive behaviors and their focal, contextual and residual stimuli through the standardized RAM-based assessment forms. The forms were completed by holding personal interviews with each participant. Then, a unique four-session care plan was developed and implemented for each participant based on his/her maladaptive behaviors and their focal, contextual and residual stimuli. The plans aimed to modify unhealthy and maladaptive behaviors and turn them into healthy and adaptive ones. Besides these four-session individual care plans, two educational sessions were held for all participants to address their joint maladaptive behaviors. For instance, educations in the area of physiological behaviors were about proper nutrition, adequate and balanced physical activity, factors affecting sleep, etc. Regarding the self-concept mode, educations were provided to make positive changes in the participants’ self-image and ideal image. In the interdependence mode, educations were mainly about peer relations and participation in group discussions and religious rituals. Finally, educations in role function mode included materials such as assuming some responsibilities in nursing homes, participating in their birthday or wedding parties and organizing and joining sport teams. To prevent information leakage from the participants in the experimental group to their counterparts in the control group, the administrators of the nursing homes settled them in separate rooms.
In the four-session personal programs, it was attempted to manipulate the focal, contextual and residual stimuli of each individual participant’s physiological, self-concept, role function and interdependence maladaptive behaviors. For instance, a participant with muscular weakness (a physiological problem) due to limited mobility (the focal stimulus) was encouraged to do physical exercise and walk. Besides, such participants were accompanied in their physical exercises. On the other hand, a participant with constipation (a physiological problem) due to limited intake of fluids and high-fiber foods (the focal stimuli) and decreased physical activity (the contextual stimulus), was provided with fruits, vegetables and fluids and was asked to perform physical activity. Finally, the elderly participants with role function and interdependence-related maladaptive behaviors were provided with counseling services by a psychologist.
During the first one month period after implementing the intervention, authors referred to the study setting and supervised the participants’ engagement in behavior modification activities. At the end of this one-month follow-up period, the participants were asked to re-complete the SF-36. For the sake of ethical considerations, the care plans were provided to the administrators and the staffs of the study setting and they were asked to use them for the participants in the control group.
One participant from the experimental group died during the study and thus, the number of elderly people in this group reduced to 29. The study data were transferred into the SPSS software. The descriptive statistics was used to present the data while the Chi-square and the paired- and the independent-sample T-tests were employed for data analysis. P-values less than 0.05 were considered as significant.
