Symptom-management Self-efficacy program, Negative symptoms, Schizophrenic patients


The purpose of this quasi-experimental research were to compare the negative symptoms of schizophrenic patients before and after receiving the symptom-management self-efficacy program, and to compare the negative symptoms of schizophrenic patients who received the symptom-management self-efficacy program with those who received regular nursing care. Research samples were 40 schizophrenic patients who met the inclusion criteria from outpatient department, Nakhon Sawan Ratchanakharin Psychiatric Hospital. They were matched by gender and negative symptoms and randomly assigned to experimental and control groups, 20 subjects each. The experimental instrument was the symptom-management self-efficacy program consisted of 4 steps: 1) Emotion arousal 2) Modeling 3) Mastery experience 4) Verbal persuasion. Data were collected using the personal patients’ record form and the positive and negative syndrome scale. All instruments were tested for content validity by 5 professional experts. The content validity index of the positive and negative syndrome scale was .84. Its inter-rater reliability was .72. Data were analyzed using mean, standard deviation and t-test. Major findings were as follow: 1. The mean score of negative symptoms of schizophrenic patients after receiving in the symptommanagement self-efficacy program was significantly lower than that before receiving the program, at the .05 level. 2. The mean score of negative symptoms of schizophrenic patients who received the symptom-management self-efficacy program was significantly lower than those who received regular nursing care, at the .05 level.
