Which of the following is a sign of maladaptive behaviour?

Neglect of personal hygiene is indeed a sign of maladaptive behaviour because it indicates a failure to maintain basic standards of self-care, which can be indicative of broader issues such as emotional distress, mental health disorders, or a lack of functioning in day-to-day life. Maladaptive behaviours often reflect an inability to cope effectively with stressors or challenges, leading to detrimental impacts on a person's health and social interactions. In contrast, options like improved work performance, active social relationships, and enhanced personal responsibility signify positive adjustments and coping strategies, showcasing an individual's ability to adapt effectively to their environment and circumstances.
