Abstract

Schizophrenia is a psychotic condition that affects individual functioning characterized by disorganized thinking, delusions, hallucinations, and maladaptive behavior. Common symptoms of schizophrenia include excessive behavioral changes such as sudden anger, screaming, and even violent behavior. The risk of violent behavior indicates the ability to harm oneself, others, and the environment. In Indonesia, the risk of violent behavior is 0.8% out of 10,000 people. With such a high rate, if left untreated, it can lead to harmful consequences such as self-injury, harm to others, and harm to the environment. Therefore, there is a need for new method or approach to prevent and reduce agitation and aggressiveness in violent behavior and to increase feelings of being cared for, respected, and honored, namely through Talk Down intervention. This study aimed to determine the effectiveness of Talk Down intervention on violent behavior in schizophrenia patients. The research design was quasi-experimental with an experimental approach using pre- post-test with a control group, with a sample size of 70 respondents selected through purposive sampling. Data were collected through questionnaires using interview and observation techniques. The results of the study showed that in the treatment group, before Talk Down intervention, the mean score was 18.26, and after Talk Down, it was 5.20. In the control group, before intervention, the mean score was 18.67, and after, it was 13.8. The Mann-Whitney U test calculation yielded an Asymp. Sig. (2-tailed) of 0.000 < 0.05. It can be concluded that Talk Down intervention is effective in reducing signs of violent behavior symptoms in schizophrenia patients in the UPIP ward of Mutiara Sukma Mental Hospital, NTB Province. It is hoped that Talk Down can be used as a nursing therapy for violent behavior patients.

Abstract

Mathematical proof is an essential competency for prospective mathematics teachers because it is closely related to reasoning and mathematical thinking skills. This study aimed to describe the profile of students' mathematical thinking errors based on Mason's thinking stages, namely entry, attack, and review, in proving mathematical principles on geometric vector topics. A quantitative descriptive approach was employed involving 44 sixth-semester Mathematics Education students. Data were collected through an essay-based mathematical proof test and analyzed using an error analysis rubric based on Mason's thinking stages. Descriptive statistics were used to calculate the frequency and percentage of errors at each stage. The results revealed that the percentages of errors at the entry, attack, and review stages were 18%, 70%, and 82%, respectively. Errors at the entry stage were mainly related to incomplete identification of given information and incorrect mathematical notation, whereas attack stage errors involved difficulties in constructing proof strategies and understanding the angle between vectors. At the review stage, students failed to verify the validity of their proofs and formulate appropriate conclusions. In conclusion, students' mathematical thinking errors were predominantly found at the attack and review stages.
