About
Definition: Schizophrenia is a chronic mental disorder that causes drastic changes in life quality and life functions, characterized by behavioural, cognitive and affective state deterioration. Therefore, it is regarded as one of the most important health problems causing both personal and economic problems around the world. Unhealthy lifestyle behaviours in individuals with chronic mental disorders, like schizophrenia, are emphasized to play a big part in physical health problems. For individuals to develop a healthy lifestyle behaviour, it is necessary to primarily determine the lifestyle behaviours and then prevent the illnesses caused by the lifestyle and deaths linked to these illnesses. Current theory or models used to benefit from health programmes, prepared for the development of healthy lifestyle behaviours, should be deep-scaled. Theories and models are guides for systematic planning and decision-making. A well-defined model could contribute to the process of effective health improvement programmes for directive and content creation. One of the models mainly used to develop a behavioural change in health and explain how to obtain the most effective health behavioural change is the "Transtheoretical Model". Objective: The study was conducted with the pretest-posttest randomized controlled trial design to detect the effect of psychoeducation on a healthy lifestyle, based on the Transtheoretical Model in an individual with schizophrenia.
The Hypotheses of the Study Hypothesis 1: When the individuals with schizophrenia who received psychoeducation based on the Transtheoretical Model are compared to the ones that did not, they will show progress in behavioural change steps.
Hypothesis 2: When the individuals with schizophrenia who received psychoeducation based on the Transtheoretical Model are compared to the ones that did not, they will have higher final test results in the healthy lifestyle scale.
Methods: The data were collected from 82 participants, as 41 intervention and 41 control. The data were collected via personal information form, behavioural change stage diagnosis form and healthy lifestyle scale II. 6-week psychoeducation, consisting of 6 modules, based on the Transtheoretical model, was applied to the intervention group. No interventions were applied to the control group. Pretests and posttests were applied to both groups.
Full description
This study is conducted in pretest-posttest randomized controlled experimental research type in a Community Mental Health Center in the south of Turkey. The population of the study are the individuals with schizophrenia who registered in a Community Mental Health Center and are under observation (N=230). The sample number is determined based on another similar study with power analysis. In the evaluation completed according to the healthy lifestyle behaviours score, the sample number needed to participate in the study was determined to be at least 42 (intervention group=21 - control group=21) in order for research results to have a meaningful effect.In order to reduce the selection bias in the determination of intervention and control groups, intervention and control groups were formed with a third person who did not have a direct role in the research from 1 to 82 using simple random sampling method. The data were collected from 82 individuals with schizophrenia, as 41 intervention and 41 control groups. The individuals with schizophrenia in the study and their families were informed according to the Helsinki Declaration and written and verbal approval were collected. The behavioural change identification form was applied to individuals with schizophrenia, who agreed to participate in the study, and their stage of the Transtheoretical Model was detected. The participants meeting the criteria in the participation stage (contemplation, preparation, action) were assigned to the intervention and control groups with the randomization. Pretests (personal information form, behavioural change identification form, Healthy Lifestyle Behaviours Scale II) were applied to the intervention and control groups before the psychoeducation. In addition to the rehabilitation activities conducted in the Community Mental Health Center, healthy lifestyle behaviours psychoeducation programme, based on the Transtheoretical Model, with 6 sessions (healthcare responsibility, nutrition, physical activity, spiritual development, interpersonal relationships, stress management) was applied to the intervention group for 6 weeks as three days in the weekdays and two sessions in a day. Psychoeducation was carried out by the researcher on the same day but within different time zones. Each psychoeducation session took 90-120 minutes with the breaks taken considering the participants' mood. After completing six sessions, the behavioural change identification form and Healthy Lifestyle Behaviours Scale II were applied to the intervention group again. On the other hand, the control group continued their rehabilitation practices prepared for themselves in the Community Mental Health Center. It was contacted with the control group three times, two face to face and one via phone. In the third and final meeting, when the intervention group's sessions are completed, the behavioural change identification form and Healthy Lifestyle Behaviours Scale II were applied again to the control group. All the participants remained in the study at the end of it. The study was completed with 41 individuals in the intervention group and 41 individuals in the control group. Statistical Package for the Social Sciences v23.0, which is a statistical analysis programme, was used to evaluate the findings of the study. It was benefited from descriptive statistics such as frequency, percentage, arithmetic average, standard deviation, minimum and maximum during data analysis. Parametric tests were used for the data analysis. The chi-squared test was used for relation analysis of two different categorized variables whereas the t-test was used while comparing averages of two independent groups. To determine the alteration of individuals' behavioural change stages before and after receiving psychoeducation, the McNemar test was used. Analysis of covariance (ANCOVA) while detecting the effect of the intervention study in the researches designed in the entrepreneurial pattern. In ANCOVA, to detect how big the effect of the independent variable on the dependent variable the eta squared (effect size) was calculated and the eta squared value (η2) was interpreted that it presents which parts of the change explain the total variant that the independent variable has on the dependent variable and it received a value. Eta squared is interpreted as 0,01 as the minor effect, 0,06 as medium effect and 0,14 as large effect. All test results were evaluated in terms of p<0.05 meaningfulness level
