Individuals with hoarding disorder exhibit heightened attachment to objects, but little is known about possible drivers of object attachment and associated object saving behaviors. Theory and preliminary evidence posit that the heightened object attachment characteristic of hoarding disorder may be partially explained by the experience of vivid, 'Proustian' memories related to objects.

There can be heterogeneity in outcomes for individuals receiving targeted CBT for voices (CBTv), and rates of drop-out require investigation. To promote the directed provision of interventions to those most likely to benefit, it is necessary to elucidate the relationship between the factors driving the variability in engagement and response to these interventions.

Perinatal obsessive-compulsive disorder (PNOCD) can impact up to one in five individuals in the perinatal period. Whilst effective treatment for PNOCD is available, parents experience barriers accessing this evidence-based psychological therapy. Healthcare professionals' perspectives on barriers to accessing support are valuable to develop targeted interventions to increase access to support for PNOCD.

Low educational literacy is associated with high rates of mental health problems. In Pakistan, only 60% of the population is literate. Traditional CBT requires literacy skills. Interventions to address the literacy barriers need to be developed.

Community crime against older people is of increasing concern but the relationship between safety-seeking behaviours and continued psychological distress has not been examined. As existing assessment tools have limited validity, we aimed to investigate this by designing a novel person-reported safety-seeking behaviour measure (PRSBM) and conducting preliminary evaluation of its wider applicability.

While around one-fifth of UK secondary school pupils exhibit clinically significant eating pathology, in-school mental health provision does not include interventions to address such eating pathology.

People experiencing psychosis in acute crisis should be offered cognitive behavioural therapy for psychosis (CBTp); however, there are few crisis-focused CBTp-informed models to underpin formulation development for people experiencing psychosis and receiving inpatient mental health care.

Approximately 24% of stroke survivors develop post-stroke depression (PSD), which is associated with poor psychological recovery, identity disruption, and reduced self-esteem. Psychological interventions often fail to address these broader challenges. The Wisdom Enhancement Timeline technique, which facilitates autobiographical reflection, has shown promise for depression in older adults. It has not yet been studied in a post-stroke population.

Intrusive re-experiencing of traumatic events is a cornerstone of post-traumatic stress disorder (PTSD). Clinicians notice that clients also experience intrusive mental images of what they think might happen during a traumatic event. As mental imagery has a powerful impact on emotion, imagination-based imagery may be implicated in the peaks of distress ('hotspots') during a trauma.

Despite their considerable public health impact, most people with depressive disorders do not receive treatment due to barriers that limit access to high-quality care. Since the onset of the COVID-19 pandemic, depressive symptoms have sharply increased, and access-to-care barriers were magnified by physical distancing requirements. Videoconferencing is a virtual care modality that reduces access-to-care barriers and can be used to deliver cognitive behavioural therapy (CBT), an evidence-based treatment for depressive disorders. However, it is unclear whether videoconference CBT effectively decreases depressive symptoms, particularly in a group therapy format.

Hallucinations and other unusual sensory experiences (USE) are common in people with psychosis. Yet access to effective psychological therapies remains limited. We evaluated if we can increase access to psychological therapy by using a brief treatment, focused only on understanding and dealing with hallucinations (Managing Unusual Sensory Experiences; MUSE), delivered by a less trained but more widely available workforce that harnessed the benefits (engaging content, standardisation) afforded by digital technology. The delivery of this in a real-world setting was considered within the non-adoption, abandonment, scale-up, spread, and sustainability (NASSS) framework.

Dissociative experiences are common transdiagnostically, and particularly prevalent in psychosis. Such experiences have long been under-recognised in routine clinical practice, despite evidence that dissociation is related to clinical complexity and increased risk of self-harm and suicidality. Adopting a symptom-specific, targeted approach to conceptualisation and intervention for dissociation may help improve outcomes.

This experimental study investigated whether the trait factors of world assumptions and cognitive flexibility were predictive of levels of attentional bias to threat stimuli, memory integration, and data-driven processing.

Cognitive behavioural therapy for fatigue (CBT-F) and insomnia (CBT-I) are effective therapies. Little is known on their effectiveness when severe fatigue and insomnia co-occur.

Defence behaviours - actions carried out to reduce perceived threat - are an important maintenance factor for persecutory delusions. Avoidance of feared situations and subtle in-situation behaviours reduce opportunities for new learning and are erroneously credited for the non-occurrence of harm; hence inaccurate fears are maintained. In contrast, exposure to feared situations whilst dropping defence behaviours - a key technique of cognitive therapy for paranoia - allows the discovery of new information concerning safety, thereby reducing persecutory delusions.

Parent depression is a well-established prospective risk factor for adverse offspring mental health. Multiple lines of evidence suggest that improvements in parent depression predicts improved offspring mental health. However, no systematic review has examined the impact on offspring of psychological treatment of purely parent depression after the postnatal period.

Fear of childbirth (FoB) is a common experience during pregnancy which can cause clinically significant distress and impairment. To date, a number of investigations of FoB have assumed that clinically significant FoB is best understood as a type of specific phobia. However, preliminary evidence suggests that specific phobia may not be the only diagnostic category under which clinically significant symptoms of FoB are best described.

Motivational Interviewing (MI) has demonstrated significant effects in diverse areas of practice, with over 2,000 controlled clinical trials published. Some criticisms of MI have emerged along the way.

Cognitive behavioural therapy (CBT) interventions are effective in reducing subjective stress. Nevertheless, the longitudinal links between mental health indicators are rarely studied in intervention research. Therefore, it is unknown how the intervention effects are sustained.

Evidence suggests that death anxiety is a transdiagnostic construct underlying numerous anxiety-related conditions. A previous phase I trial of Overcome Death Anxiety (ODA), a novel online stand-alone psychological intervention to reduce death anxiety, demonstrated preliminary evidence of efficacy and acceptability in a clinical population. However, this trial was limited by a small sample size (=20).

Specific phobia of vomiting (SPOV), also called emetophobia, is a debilitating condition that shares features with several other anxiety disorders and obsessive-compulsive disorder (OCD). Approximately half of sufferers from SPOV do not fully benefit from current treatment modalities.

The COVID-19 pandemic has had a negative impact on the population's mental health, particularly for individuals with health anxiety (HA) and obsessive compulsive disorder (OCD). This is in conjunction with a significant change in accessibility of face-to-face psychological services which have had to rapidly adapt to the remote delivery of therapy.

One of the most effective treatments for social anxiety disorder (SAD) is cognitive behavioural therapy (CBT). Prior research indicates group cohesion is connected to treatment success in group CBT for SAD (CBGT). Videoconference CBGT delivery is now common following the COVID-19 pandemic; however, research investigating treatment outcomes and group cohesion in videoconference CBGT for SAD is limited.

Although research has highlighted that suicidal imagery (SuiMI) and experiential avoidance (EA) are important in understanding suicidality, there is a need to understand how they potentially interact. Previous research has highlighted that EA potentially leads to increased cognitive intrusions, but it not known whether EA leads to increased SuiMI.

Improved understanding of the cognitive and behavioural processes underpinning panic disorder (PD) in adolescents could improve identification and treatment.

Moral injury is a potentially deleterious mental health outcome that can follow exposure to events that challenge one's moral code. Theoretical models suggest a multi-faceted self-concept may support adaptation following such events. However, little is known about the relationship between self-concept complexity and outcomes following potentially morally injurious events.

People with intellectual disability often face barriers accessing mainstream psychological services due to a lack of reasonable adjustments, including the absence of adapted versions of routine outcome measures. Adapted versions of the Patient Health Questionnaire-9 (PHQ-9) and the Generalised Anxiety Disorder-7 (GAD-7) have been created for adults with ID.

Preliminary evidence suggests that mental imagery may be an important clinical feature in hoarding. Individuals who hoard use objects as receptacles for memories, and experience more frequent, intrusive and distressing images compared with the general community. However, the specific nature of these associations remains poorly understood.

Severe fatigue following COVID-19 is a debilitating symptom in adolescents for which no treatment exists currently.

Cognitive therapy for PTSD (CT-PTSD) is an efficacious treatment for children and adolescents with post-traumatic stress disorder (PTSD) following single incident trauma, but there is a lack of evidence relating to this approach for youth with PTSD following exposure to multiple traumatic experiences.
