Abstract

People with Anorexia Nervosa (AN) have well-documented socio-emotional and neurocognitive impairments. As yet, little is known about their ability to solve problems in social situations, although a link with cognitive avoidance has been suggested. This study explored social problem-solving (SPS), using an experimental task. Secondly, the role of cognitive avoidance in SPS was investigated. Individuals with AN (n=31) and healthy controls (HC; n=39) completed the Social Problem Resolution Task which consists of problem scenarios involving awkward everyday social situations. Participants were asked to generate both the optimal solution and their personal solution. Solutions were rated in terms of how socially sensitive and practically effective they were. AN patients produced relatively poorer personal solutions compared to optimal solutions than HC participants and had higher scores on a measure of cognitive avoidance than the HC group. In AN patients, cognitive avoidance was partially associated with poor SPS. These findings suggest that whilst people with AN have no difficulty in generating socially sensitive and effective solutions to problems, but may have difficulty applying this knowledge to themselves.

Introduction

Anorexia nervosa (AN) is a serious psychiatric illness which is characterised by self-starvation, hyperactivity and being physically underweight, alongside extreme concerns about weight, shape, or eating (American Psychiatric Association, 2000). AN has the highest mortality rate of all psychiatric disorders (Hoek, 2006). Only 50–75% of those diagnosed with AN make a full recovery and around 20% become chronically ill (Steinhausen, 2009, Keel and Brown, 2010). Patients report feeling isolated and problems in the interpersonal domain are now thought central to the development and maintenance of AN (e.g. Schmidt and Treasure, 2006, Rieger et al., 2010).

Social problem solving is the process by which a person attempts to identify effective or adaptive ways of coping with everyday life problems and is an important aspect of social competence (D'Zurilla and Chang, 1995). Social problem solving is underpinned by cognitive/executive processes, such as the ability to access and manipulate prior knowledge relevant to the problem situation in working memory, the generation of appropriate strategies, inhibition of inappropriate responses and monitoring and judging the effectiveness of solutions. It is also underpinned by social/emotional skills such as empathising, taking others' perspectives and responding to feedback during decision-making (Channon, 2004). All in all, effective social problem solving requires an intricate interplay of cognitive, emotional and behavioural skills (D'Zurilla and Nezu, 1982).

Recent research suggests that people with AN have characteristic neurocognitive impairments with poor cognitive flexibility, difficulties with global processing and integrating information into context and impaired decision making (Roberts et al., 2007, Lopez et al., 2008). They also have difficulties in the social cognitive domain, including impaired emotion recognition, impaired theory of mind (which refers to one's ability to make inferences about another person's beliefs, desires and intentions) and poor regulation of emotions (e.g. Oldershaw et al., 2010). Furthermore, a recent systematic review shows preliminary evidence for the persistence of a number of these social-cognitive impairments following recovery, such as attentional biases (towards or avoiding) threatening (social) stimuli and difficulty in facial emotion recognition (Oldershaw et al., 2011a). Taken together these findings suggest that impairments in social problem solving should be a likely consequence of these neurocognitive and socio-emotional impairments in AN sufferers. Indeed, there is preliminary evidence from self-report studies suggesting that people with AN are impaired in social problem solving (Paterson et al., 2007, Paterson et al., 2010, SwansonPlease provide all the authors names in Ref. (Swanson et al., 2010) et al., 2010). However, these studies explore social problem-solving processes, rather than outcomes and as yet no experimental paradigms have been employed to explore the latter.

One other factor that will be further explored in the current study is cognitive avoidance, which refers to cognitive strategies employed to avoid negative experiences and emotions. High cognitive avoidance is thought to play a role in the development and maintenance of AN (Troop and Treasure, 1997, Schmidt and Treasure, 2006). People with AN have been shown to find the experience of having negative thoughts and feelings aversive, are fearful of revealing these to others and try to avoid distressing thoughts and feelings. Higher levels of maladaptive beliefs about the experience and expression of thoughts and feelings are associated with a greater degree of eating disorder symptomatology in AN (Hambrook et al., 2011). Moreover, high cognitive avoidance has previously been found to relate to poor social problem-solving processes in Eating Disorders (ED) (Troop et al., 1994, Troop et al., 2003, Ghaderi and Scott, 2000, Bloks et al., 2004, Paterson et al., 2010, SwansonPlease provide all the authors names in Ref. (Swanson et al., 2010) et al., 2010).

Channon and Crawford (1999) developed an experimental task investigating social problem solving in which participants are asked to generate effective solutions to real-life, socially awkward scenarios (Social Problem Resolution Task, SPRT; Channon and Crawford, 1999, Channon and Crawford, 2010, Channon et al., 2001). The SPRT consists of a series of short scenarios of social everyday situations for which participants have to generate a course of action for the main character in the story (optimal solution), as well as identify their intended course of action (personal solution). The SPRT has demonstrated impaired social problem solving in people with acquired brain injury and neurodevelopmental disorders, such as Asperger's and Tourette's Syndrome (Channon and Crawford, 1999, Channon et al., 2001, Channon, 2004).

The aims of the present study were firstly to explore social problem solving in people with AN compared to that of healthy people using the SPRT, and secondly, to study the relationship between social problem solving and cognitive avoidance.

Our main hypothesis was that individuals with AN would generate both less effective optimal and less effective personal solutions than healthy controls (HC) as measured with the SPRT. Our subsidiary hypotheses were that individuals with AN would have higher levels of cognitive avoidance compared to HCs and that cognitive avoidance would correlate with poor social problem-solving ability in the AN group.

Participants and procedure

Thirty-one female participants with AN and 39 female healthy control (HC) participants took part in this study. Participants from the AN group were recruited from the Eating Disorders in- and out-patient departments of the South London and Maudsley Hospital NHS Foundation Trust and the Barnet, Enfield & Haringey Mental Health NHS Trust. An AN diagnosis (following DSM-IV criteria) was confirmed by the patient's clinical team and by administering the Eating Disorder Examination version 16 (

Demographics

There were no overall group differences for age (AN: M=25.8, S.D.=8.6; HC: M=25.6, S.D.=10.8) t(70)=0.23, p=0.816 and IQ as measured by the NART (AN: M=114.3, S.D.=8.5; HC: M=116.7, S.D.=5.7) t(59)=1.35, p=0.182. AN participants had significantly lower BMI than those from the HC group (AN: M=16.4, S.D.=1.3; HC: M=21.5, S.D.=2.1) t(72)=12.36, p<0.001. BMI was not associated with any of the outcome variables in this study.

Clinical characteristics

As measured by EDE-Q global score, the AN group had higher levels of eating

Discussion

This is the first study to explore social problem-solving outcomes and associated processes in people with AN using an experimental study design. Our main hypothesis was partially confirmed as whilst people with AN did not differ from HCs in the quality of their optimal solutions, they did differ in terms of personal problem solving solutions.

Moreover, whilst in healthy controls there was little difference between the quality of their optimal and personal solutions, people with AN performed

      For instance, in a randomized, placebo-controlled clinical trial of women with hypothalamic amenorrhea leptin treatment resulted in improvement in gonadal, thyroid, and immune function successfully treating the disorder and restoring menstruation (Chou et al., 2011). Additionally, anorexia nervosa is associated with amenorrhea and hypoleptinemia (Mantzoros et al., 1997) and patients are described with impaired cognitive flexibility, deficient social problem solving and decreased visuospatial ability as compared to their healthy counterparts (Favaro et al., 2012; Koyama et al., 2012; Sternheim et al., 2012; Calderoni et al., 2013). However, there is no information about psychiatric aspects in anorexic women receiving leptin therapy.

      The task therefore seems into tap ‘cold’ (or more cognitive) rather than ‘hot’ (or more emotional) SC, which makes the task less difficult for patients [36]. We recently found in a social problem-solving task that patients with AN were as able as healthy controls to generate socially sensitive and practical solutions to hypothetical social scenarios, however when they had to think of themselves as one of the protagonists, they performed significantly worse than HC [43]. The only group difference on the IPT was that patients with restricting AN showed significantly poorer ability to accurately detect levels of intimacy between others.
