Summary
Staff-reported anger in individuals with intellectual disability (ID) became more accurate after interventions. Involving care staff in interventions may be therapeutically beneficial for people with ID.
Area of Science:
- Psychology
- Intellectual Disability Research
- Clinical Psychology
Background:
- Growing interest in cognitive approaches for psychological difficulties in individuals with intellectual disability (ID).
- Need to understand the properties of anger inventories and the congruence of self- and staff-reported anger levels.
- Exploration of relationships between different staff measures in assessing anger in ID populations.
Purpose of the Study:
- To investigate the psychometric properties of an anger inventory for individuals with ID.
- To examine the relationship between self-reported and staff-reported anger levels.
- To explore the relationship between different staff-based measures of anger.
Main Methods:
- Two studies were conducted using self-report and staff-report measures.
- Study 1 utilized a cross-sectional design.
- Study 2 employed a longitudinal design, including interventions.
Main Results:
- No significant relationship between self-reported and staff-reported anger at baseline.
- A significant relationship emerged on the second measurement occasion post-intervention.
- Higher correlation between self- and staff-reports when staff accompanied individuals during interventions.
Conclusions:
- Staff may need specific training or therapeutic environment exposure to accurately report anger in individuals with ID.
- The involvement of care staff in interventions appears therapeutically beneficial.
- Findings suggest potential for improved anger assessment and intervention strategies for individuals with ID through staff collaboration.

01:29Intellectual Disability
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...
01:47Aggression
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for hire...
01:30Oppositional Defiant Disorder
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

02:55Stereotypes, Prejudice, and Discrimination
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...
01:20Coping Strategies: Emotion Focused
Emotion-focused coping refers to a set of strategies aimed at managing the emotional impact of stressors, rather than directly addressing their causes. This approach involves altering one's emotional response to stressful situations to reduce their psychological effects. For example, individuals might talk with a friend or engage in activities like journaling to express their feelings. Such actions can help achieve emotional clarity or release, providing the psychological stability needed to...
