Abstract

Background:

The current study aimed to evaluate group Cognitive remediation therapy (CRT) inpatients with Anorexia Nervosa (AN). We aimed to examine the treatment response of group CRT in AN patients with high or low levels of autistic traits.

Methods:

Thirty-five in patients with an AN diagnosis received group CRT intervention for 6 sessions in a national eating disorder unit. All participants completed self-report questionnaires on thinking styles and motivation before and after the intervention.

Results:

Patients with low autistic traits had statistically significant medium size effect improvements in self-reported thinking style scales as well as confidence (ability) to change. Patients with high autistic traits showed no statistically significant improvements in any outcome measure.

Conclusions:

The brief group format CRT intervention improves self-reported cognitive and motivational aspects in people with AN without autistic traits. For patients with higher autistic traits brief group CRT does not improve self-reported cognitive style or motivation. This finding suggests that brief group format CRT might not be the best suited format for individuals with elevated autistic traits and individual or more tailored CRT should be explored.

Modeling in Therapy

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Cognitive Therapy

Cognitive Therapy

Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Operant Conditioning Intervention

Operant Conditioning Intervention

Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
In operant conditioning, behaviors that are...

Rational Emotive Behavior Therapy

Rational Emotive Behavior Therapy

Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

Autism Spectrum Disorder

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Behavior Therapy

Behavior Therapy

Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.
Exposure therapy is a cornerstone of behavioral treatment for anxiety disorders. It involves systematic exposure to feared stimuli, either in real...
