Even if there is an initial improvement in response to treatment, this is often followed by relapse, with an increasing risk of relapse after every depressive episode [5]. The anxious and depressed groups showed an attentional bias towards supraliminal negative words, in comparison with normal controls. This pattern indicates that for both presentation times the mixed MDD/AD group showed more variability in AB for general threat words than the comparison group, whereas the rMDD group also showed more variability in AB for general threat words than the comparison group but only for short duration trials (500 ms). 0.35), p = .42, 95% CI [-0.36; 1.34], d = 0.24) did not differ significantly from the comparison group. The 2-year follow-up assessment included a wide range of outcome measures. Building further on previous concepts and measurements of AB, these authors proposed trial-level bias scores (TL-BS) representing variance in AB towards the target stimuli, variance in AB away from the target stimuli, maximum AB towards the target stimuli, maximum AB away from the target stimuli, and overall variability in AB towards and away from the target stimuli. A Monte Carlo simulation study demonstrated that TL-BS indices could be prone to result in false positive group differences; the differences between groups might in fact reflect differences in mean RT and or differences in overall SD [33]. See Table 5 for zero-order correlations. Attentional bias toward threatening or emotional information is considered a cognitive marker of anxiety, and it has been described in various clinical and subclinical populations. Because these processes might play a different role in MDD, it would be interesting in future research to use a task that is especially designed for this (e.g., the Attentional Response to Distal vs. Proximal Emotional Information) [60]. 0.20), p = .75, 95% CI [-0.31; 0.68], d = 0.07) showed significantly higher scores than the comparison group. In addition, an earlier study using a visual probe task depicting words, found that participants who were diagnosed with Dysthymia or MDD showed an AB for socially threatening words [19]. Depressive symptoms were assessed using the 30-item Inventory of Depressive Symptoms Self-Report version (IDS-SR) [40]. These studies seem to support the hypothesis that even after recovery of depression, heightened AB for negative and lowered AB for positive information remains, possibly increasing the risk of relapse or recurrence. Interestingly, the results of this re-analysis showed that rMDD participants were characterized by higher levels of TL-BS, specifically increased variability, than non-depressed individuals. Visualization, Therefore, more positive AB scores (i.e., stronger cue validity effects) were indicative of a stronger attentional bias towards the emotional information. 0.16), p = .21, 95% CI [-0.27; 1.49], d = 0.13) showed significantly stronger variability than the comparison group. This topic continues to inspire the development of new tasks and training paradigms that have … At shorter presentation times of the cues (100–300 ms), faster responding is generally found on validly cued trials compared to invalidly cued trials, a finding that is referred to as the “cue validity” or cue facilitation effect. Writing – review & editing. Attentional bias is described as the preferential attention toward certain types of (emotional) information in the environment. This is consistent with the view that threat bias is a premorbid characteristic that heightens the risk for the development of ADs, although it may also reflect a symptom of AD or the relatively high severity of the mixed group’s condition. Participants also completed trait and state psychological measures and provided saliva samples for cortisol analysis. For the correct trials and missing pairs in calculating TL-BS per stimulus type per presentation time, see S3 Appendix. For the other indices of threat stimuli there were no significant between group differences (Threat Away 500 ms F (3,734) = .62, p = .60 partial η2 = .003; Threat Towards 1250 ms F (3,734) = 1.89, p = .13, partial η2 = .008). For more information about PLOS Subject Areas, click Writing – review & editing, Affiliations Together, these findings point to the relevance of using different categories of emotionally relevant stimuli to examine AB in depression. A white rectangle placeholder was presented (4 cm high x 10.5 cm long), both on the left and the right side of this fixation cross. Paired trials that were more than 9 trials apart were discarded. In this way we were able to examine whether the pattern of AB in pure MDD participants differed from that in individuals with comorbid AD. ADs were generalized anxiety disorder, panic disorder, social phobia, and agoraphobia. Supervision, This study aims to investigate the acute and chronic effects of a dietary intervention of 22 g freeze-dried whole wild blueberry powder. However, systematic reviews point to limited efficacy in terms of remission, response rates and long-term effects for both pharmacological [1] … The current study also failed to corroborate the findings of an earlier small-scale visual probe study (using 500 ms presentation time) among individuals with dysthymia (n = 13) or MDD (n = 7) indicating that these participants were characterized by a vigilance for adjectives that were very similar to the ones used in the current study (e.g., inadequate, useless, stupid, inept) [19]. [55]), this AB may reflect a heightened sensitivity for negative adjectives. In the current emotional modification of this paradigm, the emotional value of the cue is varied (i.e., emotional vs. neutral) which allows to investigate AB for disorder-relevant emotional information (with the responses to the neutral trials as the reference category and the comparison control participants as the reference group). 0.25), p < .01, 95% CI [0.29, 1.65], d = 0.31. Project administration, With the advent of attentional bias modification techniques (Mathews & MacLeod, 2002), it became possible to modify attentional bias experimentally. For Threat 500 ms F (3,871) = 5.16, p = .002, partial η2 = .01 and for Threat 1250 ms F (3,871) = 4.85, p = .002, partial η2 = .009 there was a significant difference between groups. Table 4 shows the significant post hoc contrasts for the analyses of the traditional AB scores as well as of the TL-BS indices. (2018) Attentional bias for negative, positive, and threat words in current and remitted depression. Funding: The infrastructure for the NESDA study (www.nesda.nl) has been funded through the Geestkracht program of the Netherlands Organisation for Health Research and Development (Zon-Mw, grant number 10-000-1002;http://www.zonmw.nl/en/) and participating universities (VU University Medical Center, Leiden University Medical Center, University Medical Center Groningen). In these trials, instead of a word cue, a digit appeared for 100 ms at the location of the fixation cross. Subsequent research among nonclinical participants found similar results [25] suggesting that AB in depression may reflect a difficulty in disengaging from negative information rather than enhancing orientation/engagement. The relatively slow reaction times on validly cued trials indicate an inhibition of return effect. However, findings concerning the presence of these biases in depression are mixed. Writing – review & editing, Affiliation Cues were 16 generally threatening words, 16 neutral words, 16 negative adjectives, and 16 positive adjectives (see Table 1). In a similar vein, both dysphoric and rMDD individuals spent significantly less time attending to positive images (such as scenes of people smiling, or kittens) and more to depression-images (e.g., scenes of people appearing sad, unhappy, or images of neglected animals, etc.)
