The Effectiveness of Therapy Administered by Mental Health Nurses (TKN) as an Intervention to Alleviate Hallucinatory Symptoms among Kota Tasikmalaya Indonesia

Abstract

Background. In the context of acute psychiatric care characterized by severe hallucinatory symptoms, providing timely and effective interventions poses challenges. Therapy administered by Mental Health Nurses (TKN) emerges as a promising solution to comprehensively address these acute symptoms. This therapeutic approach is designed to alleviate hallucination symptoms during the acute phase.

Objectives. This study aimed to investigate the effectiveness of Therapy administered by Mental Health Nurses (TKN) as an intervention tailored for individuals facing acute hallucinatory challenges. The overarching goals include exploring the therapeutic dimensions of the intervention, assessing the potential for tailored interventions based on demographic factors, and translating findings into practical implications for mental health professionals.

Methods. This study used a quasi-experimental design with a one-group pre-post-test structure. A total of 117 participants diagnosed with schizophrenia from outpatient psychiatric wards were selected in community setting, excluding individuals with concurrent mental retardation to maintain sample homogeneity. Data collection, conducted over two months from July to August 2023, included a pre-test assessment before any intervention to establish baseline hallucinatory symptoms. Therapy by Mental Health Nurses (TKN) was administered over two weeks, consisting of four 30- to 45-minute sessions for each participant. After each session, participants underwent reassessment for hallucinatory symptoms, totaling five assessments. Psychotic Syndrome Rating Scale (PSYRAT) was used to measure hallucination scores. The data analysis employed paired t-tests for baseline and post-intervention scores within a two-week period. A Repeated Measures Analysis of Variance (ANOVA) assessed the effect of interventions on hallucination scores, with age, gender, and adherence status as factors. Post hoc analyses, including pairwise comparisons, identified specific subgroup differences and assessed the time effect within the same group.

Results. The study cohort primarily consisted of adults (90.6%), maintaining a balanced gender distribution with 51.3% males and 48.7% females. A substantial portion had low educational backgrounds (59%), and the majority were unemployed (87.2%), with family members serving as the predominant primary caregivers (87.2%). Regarding medication adherence, over half adhered to the prescribed regimen (52.1%). Results demonstrated an improvement in hallucination symptoms for adolescents and the elderly compared to adults. While gender and adherence status did not individually influence symptoms significantly, age category emerged as a significant contributing factor (F = 3.991, p = 0.021). Interaction effects emphasized the substantial influence of time on symptom shifts over the intervention (F = 24.164, p <0.001). Particularly, the mean difference of 4.636 (p <0.001) from Time 1 to Time 5 signified a substantial decrease in hallucination scores, highlighting the cumulative impact of the therapy. These findings underscore the effectiveness of Therapy administered by Mental Health Nurses (TKN) across diverse demographic factors, providing valuable insights for tailored interventions in psychiatric emergencies.

Conclusion. Therapy administered by Mental Health Nurses (TKN) demonstrates effectiveness in reducing schizophrenia symptoms, especially among adolescents and the elderly. The impact of time on the intervention's effectiveness is notable, with a cumulative effect observed over the intervention period. Sustained and consistent engagement with the therapy leads to more substantial improvements in hallucination symptoms. Therefore, tailored interventions considering age are crucial for optimal effectiveness. This understanding enables practitioners to optimize the therapy schedule, aligning it with the natural progression of symptom alleviation.
