In the present article, we present four experiments in which we examined whether mental imagery can initiate retrieval-induced forgetting. Participants were presented with word pairs (Experiments 1, 2, and 3) or narratives (Experiment 4) and then engaged in selective mental imagery about half of the details from half of the categories. The results indicated that mental imagery can produce the same pattern of impairment as retrieval practice (Experiment 1) and postevent questioning (Experiment 4). Additionally, mental imagery-invoked, retrieval-induced forgetting was found for category cued recall (Experiments 1, 3, and 4) and cued recall (Experiment 2); it was found to dissipate across a 24-h delay, but only when there was no pre-delay test (Experiment 3). Such retrieval-induced forgetting was also found for imagining from the first-person and third-person perspectives (Experiment 4). From these findings, we suggest that the underlying retrieval processes behind mental imagery can initiate retrieval-induced forgetting. The findings are discussed in terms of inhibitory processes

IntroductionPrevention of suicide is a global public health challenge extending beyond mental health services. Linking routinely collected health and social care system data records for the same individual across different services and over time has enormous potential in suicide research. Most previous research linking suicide mortality data with routinely collected electronic health records involves only one or two domains of healthcare provision such as psychiatric inpatient care. This protocol paper describes the development of a population-based, routinely collected data linkage study: the Suicide Information Database Cymru (SID-Cymru). SID-Cymru aims to contribute to the information available on people who complete suicide.Methods and analysisSID-Cymru will facilitate a series of electronic case–control studies based in the Secure Anonymised Information Linkage (SAIL) Databank. We have identified 2664 cases of suicide in Wales between 2003 and 2011 from routinely collected mortality data using International Classification of Diseases, Tenth Revision, codes X60–X84 (intentional self-harm) and Y10–Y34 (undetermined intent). Each case will be matched by age and sex to at least five controls. Records will be collated and linked from routinely collected health and social data in Wales for each individual. Conditional logistic regression will be applied to produce crude and confounder (including general practice, socioeconomic status) adjusted ORs.Ethics and disseminationThe SAIL Databank has the required ethical permissions in place to analyse anonymised data. Ethical approval has been granted by the Information Governance Review Panel (IGRP). Findings will be disseminated through peer-reviewed publications, consultations with stakeholders and national/international conference presentations. The improved understanding of the prior health, nature of previous contacts with services and wider social circumstances of those who complete suicide will assist in prevention policy, service organisation and delivery. SID-Cymru is funded through the National Institute for Social Care and Health Research, Welsh Government (RFS-12-25).

Background Depression and debt are common in the UK. Debt Counselling for Depression in Primary Care: an adaptive randomised controlled pilot trial (DeCoDer) aimed to assess the clinical effectiveness and cost-effectiveness of the addition of a primary care debt counselling advice service to usual care for patients with depression and debt. However, the study was terminated early during the internal pilot trial phase because of recruitment delays. This report describes the rationale, methods and findings of the pilot study, and implications for future research. Objectives The overarching aim of the internal pilot was to identify and resolve problems, thereby assessing the feasibility of the main trial. The specific objectives were to confirm methods for practice recruitment and the ability to recruit patients via the proposed approaches; to determine the acceptability of the study interventions and outcome measures; to assess contamination; to confirm the randomisation method for main trial and the level of participant attrition; and to check the robustness of data collection systems. Design An adaptive, parallel, two-group multicentre randomised controlled pilot trial with a nested mixed-methods process and economic evaluation. Both individual- and cluster (general practice)-level were was used in the pilot phase to assign participants to intervention or control groups. Setting General practices in England and Wales. Participants Individuals were included who were aged ≥ 18 years, scored ≥ 14 on the Beck Depression Inventory II and self-identified as having debt worries. The main exclusion criteria were being actively suicidal or psychotic and/or severely depressed and unresponsive to treatment; having a severe addiction to alcohol/illicit drugs; being unable/unwilling to give written informed consent; currently participating in other research including follow-up phases; having received Citizens Advice Bureau (CAB) debt advice in the past year; and not wanting debt advice via a general practice. Interventions The participants in the intervention group were given debt advice provided by the CAB and shared biopsychosocial assessment, in addition to treatment as usual (TAU) and two debt advice leaflets. The participants in the control group were given advice leaflets provided by the general practitioner and TAU only. Main outcome measures (1) Outcomes of the pilot trial – the proportion of eligible patients who consented, the number of participants recruited compared with target, assessment of contamination, and assessment of patient satisfaction with intervention and outcome measures. (2) Participant outcomes – primary – Beck Depression Inventory II; secondary – psychological well-being, health and social care utilisation, service satisfaction, substance misuse, record of priority/non-priority debts, life events and difficulties, and explanatory measures. Outcomes were assessed at baseline (pre-randomisation) and at 4 months post randomisation. Other data sources – qualitative interviews were conducted with participants, clinicians and CAB advisors. Results Of the 238 expressions of interest screened, 61 participants (26%) were recruited and randomised (32 in the intervention group and 29 in the control group). All participants provided baseline outcomes and 52 provided the primary outcome at 4 months’ follow-up (14.7% dropout). Seventeen participants allocated to the intervention saw a CAB advisor. Descriptive statistics are reported for participants with complete outcomes at baseline and 4 months’ follow-up. Our qualitative findings suggest that the relationship between debt and depression is complex, and the impact of each on the other is compounded by other psychological, social and contextual influences. Conclusions As a result of low recruitment, this trial was terminated at the internal pilot phase and was too small for inferential statistical analysis. We recommend ways to reduce this risk when conducting complex trials among vulnerable populations recruited in community settings. These cover trial design, the design and delivery of interventions, recruitment strategies and support for sites. Trial registration Current Controlled Trials ISRCTN79705874.

This is the accepted version of the paper.This version of the publication may differ from the final published version. Permanent repository link AbstractThe Affect Infusion Model (AIM) is a prominent theory of when current emotional state is expected to influence the interpretation of a social stimulus (situation). We discuss the assumptions in AIM and conclude that its current specification predicts that both deliberation time and situational complexity should lead to affect infusion.The aim of this research was to clarify the relative importance of these factors in determining affect infusion, and hence aid the further development of AIM. We present an experimental design in which situational complexity and deliberation time can be manipulated orthogonally as independent factors. Our results show that it is the latter factor, but not the former, which can influence the degree of affect infusion. According to AIM, when interpreting a novel social situation, affect infusion is defined to occur when our current emotional state leads to an interpretation of the situation specifically congruent with this emotional state (cf. Bower, 1981;Forgas, 1995a;Isen, Shalker, Clark, & Karp, 1978). For example, consider a scene of a man and a woman talking to each other, such that there are no cues as to whether this is a happy/excited interaction or an unhappy/angry one. Affect infusion would occur if people in (say) an unhappy mood would be more likely to offer unhappy interpretations-this is the basis of our experimental investigation.Forgas (1995a) proposed that there are four relevant (i.e., when it comes to considering possible interactions between cognition and emotion) modes of cognitive processing; knowing which mode of cognitive processing applies in a given situation can help predict whether affect infusion will occur or not ( Figure 1). First, a person can access information about a belief already held; in such cases, an emotional valence may already be attached to a belief and therefore there would be little scope for the current emotional state to affect perception of the belief (this mode is referred to as 'direct access'). For example, the attitude towards environmental issues of a committed environmentalist will not be affected by her current state of mind. Second, there are situations where information processing takes place in order to accomplish a specific goal, and so an effort would be made to specifically suppress potential emotional influences (this is the 'motivated processing' mode Kunda, 1990). An example of this is the finding of Bower (1981;Isen, 1984), whoshowed that participants in an unhappy mood are more likely to recall unhappy episodes etc.The third and fourth modes of cognitive processing are considered 'constructive', in the sense that a person's reliance on existing knowledge representations, e.g., for understanding a novel social situation, is limited; therefore, novel representations have to be constructed from the combination of stored information and new stimulus details (Fiedler, 19...
