The Effect of Designed SIA Instrument Supported Interpersonal Relations-Based Group Practice on Psychological Well-Being and Creativity: A Randomized, Single-Blind, Placebo-Controlled Study

This research was carried out to examine the effect of group practice based on interpersonal relations supported by the designed SIA instrument on psychological well-being and creativity.

In a single-blind randomized controlled trial, a 3x4 split-plot design was used. The sample group was determined in two stages. The target group consisted of those who had scores lower than the mean scores of the Psychological Well-Being Scale (PWS) total score obtained from the nursing students who accepted to participate in the study. A stratified randomization was carried out according to gender with 30 students who met the criteria for inclusion in the sample from the determined target group. The study was conducted with a total of 30 students, 10 of whom were in the intervention group, 10 in the placebo control group, and 10 in the control group. Research data were collected with Descriptive Information Form, Psychological Well-Being Scale (PWS) and Creativity Scale (CS). A group application based on Peplau's Interpersonal Relations Theory, supported by the SIA instrument, was applied to the individuals in the intervention group. It is a rhythm instrument with a water effect sound, designed by SIA researchers and has a national utility model registration certificate. Music therapy techniques were also used in practice. The application was completed in a total of six weeks, one session per week. The placebo control group application was carried out simultaneously with the intervention group application, and the group application without active curative content was applied. No intervention was applied to the control group. In order to evaluate the data, PWS and SR were applied at time series points (pretest, posttest, 1st month follow-up and 3rd month follow-up).

In the analysis of the data, Descriptive statistics, Normal distribution of the data related to continuous variables were evaluated with the Shapiro Wilk test of normality. One-way analysis of variance (ANOVA) or Kruskal-Wallis H test was used to compare the variances of more than two independent groups when the assumption of normality of continuous variables was met. Repeated measures ANOVA (repeated measure ANOVA) was used when the assumption of normality was provided in the in-group and between-group comparisons for repeated measures. In the absence of normality, the nonparametric test (Nonparametric Tests for the F1-LD-F1 Design) was used for repeated measurements. In cases where the group*time interaction was significant, evaluations independent of the time effect were made and repeated measures ANOVA and Friedman tests were used. A value of p<0.05 was considered statistically significant.
