Best practice guidelines recommend CBT for everyone with psychosis, yet high rates of non-engagement and early drop-out result in many not receiving ‘full dose’ therapy. For those who do engage, effect sizes are typically modest. Most people with psychosis have an insecure attachment style, characterised by predictable and problematic patterns of beliefs, emotion regulation and interpersonal behaviours, including help-seeking. Attachment-congruent adaptations to CBT could improve retention and recovery outcomes for people who are also insecurely attached.

This is the first evaluation of attachment-congruent adaptations to CBT for psychosis. We assessed impact of therapy for the first five people (aged 30–50) to complete therapy and measures.

We used a single case ABC design and measured paranoia, voices, help-seeking, coping, and personal goals over baseline, intervention, and follow-up phases. We predicted that adapted CBT would lead to improved outcomes which would be maintained at follow-up. Trait measures of voices, paranoia, attachment, and recovery are used to describe the sample.

Participants presented with complex needs, including paranoia, voices, and attachment insecurity. Baseline phases showed high and variable levels of psychosis. All showed improvements in paranoia, voices, willingness to seek help, ability to cope, and/or personal recovery goals over the intervention phase. Gains were largely maintained or improved further at follow-up.

Attachment-congruent adaptations to CBT are likely to benefit people with psychosis who present with the additional cognitive, affective and behavioural complexities characteristic of insecure attachment, which threaten access and impact of recommended treatments if not addressed.

Outcome studies of the treatment of compulsive buying disorder (CBD) have rarely compared the effectiveness of differing active treatments.

This study sought to compare the effectiveness of cognitive behavioural therapy (CBT) and person-centred experiential therapy (PCE) in a cross-over design.

This was an ABC single case experimental design with extended follow-up with a female patient meeting diagnostic criteria for CBD. Ideographic CBD outcomes were intensively measured over a continuous 350-day time series. Following a 1-month baseline assessment phase (A; 28 days; three sessions), CBT was delivered via 13 out-patient sessions (B: 160 days) and then PCE was delivered via six out-patient sessions (C: 63 days). There was a 99-day follow-up period.

Frequency and duration of compulsive buying episodes decreased during active treatment. CBT and PCE were both highly effective compared with baseline for reducing shopping obsessions, excitement about shopping, compulsion to shop and improving self-esteem. When the PCE and CBT treatment phases were compared against each other, few differences were apparent in terms of outcome. There was no evidence of any relapse over the follow-up period. A reliable and clinically significant change on the primary nomothetic measure (i.e. Compulsive Buying Scale) was retained over time.

The study suggests that both CBT and PCE can be effective for CBD. Methodological limitations and suggestions for future CBD outcome research are discussed.

Cognitive behavioural therapy (CBT) for psychosis currently yields modest outcomes and must be improved. Attachment imagery may be an effective means of reducing severity of paranoid beliefs and associated affect. Experimental studies have demonstrated these effects in non-clinical groups. The impact in clinical populations remains untested.

This study assessed the impact of a brief attachment imagery task on paranoia and mood, in two people with a diagnosis of schizophrenia.

Two single case studies are presented. Both participants were working age adults with persecutory delusions. The study utilised an A-B-A design. Participants were recruited for a 6-week period, with a 2- and 3-week baseline respectively, 1-week intervention phase, and follow-up phase matched to duration of baseline. Trait paranoia and attachment were measured at the start of the baseline. State paranoia and affect were measured daily over the 6-week period.

For both participants, the baseline phase was characterised by high and variable levels of paranoia, which reduced during the intervention phase, with a return to baseline scores at follow-up. We found a similar pattern for negative affect, and the reverse pattern for positive affect.

Attachment imagery may function as an effective emotion regulation strategy for people with psychosis. Continued use is likely to be needed to maintain gains. This brief task could prove valuable to people needing skills to manage paranoia and mood, and give clinicians confidence that people can manage short-term distress in CBT for psychosis, for example when addressing past trauma.
