Autobiographical Memory Specificity and Emotional Disorder

The authors review research showing that when recalling autobiographical events, many emotionally disturbed patients summarize categories of events rather than retrieving a single episode. The mechanisms underlying such overgeneral memory are examined, with a focus on M. A. Conway and C. W. Pleydell-Pearces (2000) hierarchical search model of personal event retrieval. An elaboration of this model is proposed to account for overgeneral memory, focusing on how memory search can be affected by (a) capture and rumination processes, when mnemonic information used in retrieval activates ruminative thinking; (b) functional avoidance, when episodic material threatens to cause affective disturbance; and (c) impairment in executive capacity and control that limits an individuals ability to remain focused on retrieval in the face of distraction.

Construction and factorial validation of a short form of the Self-Compassion Scale.

The objective of the present study was to construct and validate a short-form version of the Self-Compassion Scale (SCS). Two Dutch samples were used to construct and cross-validate the factorial structure of a 12-item Self-Compassion Scale-Short Form (SCS-SF). The SCS-SF was then validated in a third, English sample. The SCS-SF demonstrated adequate internal consistency (Cronbachs alpha ≥ 0.86 in all samples) and a near-perfect correlation with the long form SCS (r ≥ 0.97 all samples). Confirmatory factor analysis on the SCS-SF supported the same six-factor structure as found in the long form, as well as a single higher-order factor of self-compassion. The SCS-SF thus represents a reliable and valid alternative to the long-form SCS, especially when looking at overall self-compassion scores.

Autobiographical memory specificity and affect regulation: an experimental approach.

This study investigated J. M. G. Williamss (1996) affect-regulation hypothesis that level of specificity of autobiographical memory (AM) is used to minimize negative affect. It was found that a negative event leads to more reports of subjective stress in high- as compared with low-specific participants. Also, afterward, high-specific participants rated their unprompted memories for the event as more unpleasant. The results indicate that, relative to high specificity, being less specific in the retrieval of AMs is associated with less affective impact of a negative event. Results are discussed within the affect-regulation model. It is suggested that future research take a more functional perspective on AM specificity.

Mindfulness and reduced cognitive reactivity to sad mood: evidence from a correlational study and a non-randomized waiting list controlled study.

Cognitive Reactivity (CR) refers to the degree to which a mild dysphoric state reactivates negative thinking patterns, and it has been found to play a key causal role in depressive relapse. Although Mindfulness-Based Cognitive Therapy (MBCT) directly aims to address this mechanism of CR, the relationship between mindfulness and CR has not been tested to date. Using a cross-sectional design (Study 1; n = 164) and a non-randomized waiting list controlled design (Study 2; MBCT [n = 18] vs. waiting list [n = 21]), the authors examined the relationship between naturally occurring levels of mindfulness (Study 1) and MBCT (Study 2) on the one hand, and CR on the other hand. In line with predictions, it was found that (a) trait mindfulness is significantly negatively correlated with CR, even when controlled for current depressive symptoms and prior history of depression (Study 1), and that (b) MBCT, compared to a matched control group, significantly reduces CR, and that this effect of MBCT on reduction of CR is mediated by a positive change in mindfulness skills (Study 2). Results provide first evidence for the claim that mindfulness practices in MBCT are designed to address the process of CR.

Reduced autobiographical memory specificity and rumination in predicting the course of depression.

Reduced autobiographical memory (AM) specificity is a known vulnerability factor for depression. AM specificity was investigated as a predictor of depression with the Autobiographical Memory Test (J. M. G. Williams & K. Broadbent, 1986). When baseline depression scores were partialed, reduced AM specificity to negative cue words predicted higher levels of depression at 7-month follow-up. Once rumination was taken into account by means of the Rumination on Sadness Scale (M. Conway, P. A. R. Csank, S. L. Holm, & C. K. Blake, 2000), AM specificity no longer predicted depression, suggesting that the predictive value of AM specificity observed in previous studies might be--at least partly--explained as an effect of rumination. Further mediation analyses indeed revealed support for rumination as a mediator of the relation between reduced AM specificity and poor outcome of depression.

Reduced autobiographical memory specificity and affect regulation.

The effect of specificity of autobiographical memory (AM) retrieval on the affective impact of an emotional event was examined. In Study 1 (N = 90) the impact of a negative and positive experience was compared between student participants who habitually retrieve autobiographical memories (AMs) in a specific way and participants who generally retrieve less specific memories. In Study 2 (N = 48) the effect of an experimentally induced (specific vs. overgeneral) retrieval style on the impact of a negative experience was studied in student participants who habitually retrieve less specific memories. Study 1 replicated the finding of Raes, Hermans, de Decker, Eelen, & Williams (2003) that a negative event leads to less subjective distress in low‐specific participants as compared with high‐specific participants. However, both groups did not differ in their affective reaction to a positive event. Important, reduced memory specificity was associated with “repressive coping”, providing further evidence for the idea that reduced memory specificity is used as an avoidant or repressive‐defensive mechanism to regulate negative affect (Williams, 1996). In Study 2, participants who were induced to retrieve memories in an overgeneral way experienced more distress following a negative event as compared with participants who were induced to retrieve memories in a specific way. Results are discussed in the context of recent findings concerning AM specificity and emotion regulation (Philippot, Schaefer, & Herbette, 2003). Directions for further research are suggested.

A sentence completion procedure as an alternative to the Autobiographical Memory Test for assessing overgeneral memory in non-clinical populations

Overgeneral memory (OGM) has been proposed as a vulnerability factor for depression (Williams et al., 2007) or depressive reactivity to stressful life-events (e.g., Gibbs & Rude, 2004). Traditionally, a cue word procedure known as the Autobiographical Memory Test (AMT; Williams & Broadbent, 1986) is used to assess OGM. Although frequently and validly used in clinical populations, there is evidence suggesting that the AMT is insufficiently sensitive to measure OGM in non-clinical groups. Study 1 evaluated the usefulness of a sentence completion method to assess OGM in non-clinical groups, as an alternative to the AMT. Participants were 197 students who completed the AMT, the Sentence Completion for Events from the Past Test (SCEPT), a depression measure, and visual analogue scales assessing ruminative thinking. Results showed that the mean proportion of overgeneral responses was markedly higher for the SCEPT than for the standard AMT. Also, overgeneral responding on the SCEPT was positively associated to depression scores and depressive rumination scores, whereas overgeneral responding on the AMT was not. Results suggest that the SCEPT, relative to the AMT, is a more sensitive instrument to measure OGM, at least in non-clinical populations. Study 2 further showed that this enhanced sensitivity is most likely due to the omission of the instruction to be specific rather than to the SCEPTs sentence completion format (as opposed to free recall to cue words).

Reduced autobiographical memory specificity as an avoidant coping style.

OBJECTIVE Previous studies suggest that reduced autobiographical memory specificity might serve as a way of regulating affect. This study examined the relationship between autobiographical memory specificity and avoidant coping. METHOD Sixty students completed the Autobiographical Memory Test (AMT). Different types of avoidant coping were assessed using questionnaires: the Acceptance and Action Questionnaire, the Cognitive-Behavioural Avoidance Scale and the White Bear Suppression Inventory. RESULTS For all questionnaires, a significant correlation was observed between the number of specific responses on the AMT and an avoidant coping style. More avoidance was associated with fewer specific answers. These correlations remained when corrected for number of omissions. CONCLUSION The results provide further evidence for the affect-regulating quality of autobiographical memory specificity.

Trauma and autobiographical memory specificity in depressed inpatients

Research on autobiographical memory has shown that clinical depression is associated with a difficulty in retrieving specific autobiographical memories in response to cue words. This study examined the relation between lack of autobiographical memory specificity and self-reported trauma in a group of depressed adults (N = 23). In addition to the Autobiographical Memory Test (AMT; Williams & Broadbent, 1986) participants completed a number of questionnaires assessing the presence of traumatic experiences in the past, level of depression and neuroticism. The number of specific responses was not related to depression severity, but was significantly associated with the presence and severity of reported physical abuse. Participants who had been victim of physical abuse were less specific than participants who had not been confronted with such physical adversities. The results are discussed in the context of a functional hypothesis about the developmental relations between memory specificity, trauma and depression.

Dampening of positive affect prospectively predicts depressive symptoms in non-clinical samples

Past research has convincingly shown that a ruminative response style to negative affect (NA) predicts concurrent and prospective levels of depressive symptoms. Recent findings suggest that how people respond to positive affect (PA) might also be involved in the development of depressive symptoms, although this has heretofore not been tested prospectively. Participants from two non-clinical samples (total N=487) completed measures of depressive symptoms, response styles to NA (negative rumination) and response styles to PA (positive rumination and mood dampening) at two assessments separated by a 3-month (Sample 1) and 5-month period (Sample 2). Results in both samples showed that increased dampening responses to PA predict depressive symptoms at follow-up, even when taking into account baseline depressive symptoms and ruminative responses to NA. The results suggest that (dampening) responses to PA add useful information above and beyond (ruminative) responses to NA in predicting depression symptoms prospectively.
