Abstract

Forty-two patients with spider phobia, fulfilling the DSM-III-R criteria for simple phobia, were assessed with behavioral, physiological and self-report measures. They were randomly assigned to two group treatment conditions: (1) small groups of three to four patients, and (2) large groups of seven to eight patients. They received one 3-hr session consisting of exposure and modeling. The results showed that both conditions yielded significant improvements on almost all measures, and these were maintained or furthered at the 1-yr follow-up. With one exception, there was no difference between the conditions, but on most measures there was a trend for the small group condition to yield better effects. The proportions of clinically significantly improved patients at post-treatment were 82% in the small group and 70% in the large group. At follow-up the corresponding figures were 95% and 75%, respectively. The conclusion that can be drawn is that one-session group treatment is a feasible alternative to individual treatment, yielding almost as good effects.

The relative efficacy and efficiency of single- and multi-session exposure therapies for specific phobia: A meta-analysis

Intervention format (group vs. individual). Although individually delivered therapy is a more commonly studied format, the efficacy of group therapy has been examined in both OST (e.g., Öst, 1996) and multi-session (e.g., Teachman & Woody, 2003) exposure studies. Given the purported potential benefits of group-based exposures, such as increased service accessibility and group encouragement (Li et al., 2020), it would be beneficial to determine whether treatment effects are greater when therapy is delivered in a group or individual format.
Exposure therapy is the preferred treatment for specific phobia (SP), with evidence supporting its efficacy whether delivered over multiple sessions or as a single session, such as One-Session Treatment. In this meta-analysis, we compared the efficiency and effectiveness of single- and multi-session exposure for SP. PsycINFO, Embase, MEDLINE, and Cochrane were systematically searched for peer-reviewed articles reporting the effects of multi-session (k = 30) and/or single-session (k = 55) in vivo exposure on SP symptoms in clinical populations (n = 1758 participants). A random-effects model was used to synthesise and compare the pre-post treatment effects (Hedges’ g) on approach behaviour and self-reported SP symptoms. Mean total treatment time was significantly longer for multi-session exposure than for single-session. There were no significant differences in the pooled effect sizes of single-session and multi-session exposure at post-treatment and follow-up assessments; effect sizes were large for all outcomes. Phobia subtype significantly moderated the effect size for both treatment approaches, although the direction of association differed according to the outcome measures. Results suggest no evidence for differences in the effectiveness of single- and multi-session exposure, but single-session is more time efficient. These outcomes suggest that policies to facilitate access to single-session exposure would be beneficial.
An online spider game: Overcome your fear, exposure is near
2022, Computers in Human Behavior Reports
Spider-fearful people tend to avoid spiders, resulting in maintaining their phobia. However, some people can overcome their fear and approach spiders. This approach might be key in the reduction of fear and avoidance behaviour. The aim of this study was to examine the effect of approach-avoidance behaviour on (changes in) spider fear and avoidance. Participants (n = 122) with varying levels of spider fear played the online “collect the coins” game. In this game, participants had to collect 100 coins by clicking on different symbols. One symbol always resulted in one coin (safe option); another symbol mostly resulted in a large reward (3 coins), but sometimes in a spider (risky option). Participants rated the digital spider on evoked fear, disgust, and distress. Spider fear was measured with the fear of spiders questionnaire (FSQ). Avoidance was measured via symbol selection, self-reported avoidance, and a digital behavioural avoidance test, dBAT. Higher FSQ scores correlated with more self-reported spider-fear, -distress and -disgust, and larger dBAT-distances. Additionally, higher FSQ scores correlated with less risky- and more safe-selections. Importantly, more risky selections resulted in a stronger decrease in self-reported spider-fear and -disgust, whereas safe selections increased these emotions. Future studies are necessary to test if this link between approach-avoidance behaviour and emotional changes holds for spider phobics and real spiders.
Large-group one-session treatment: Feasibility and efficacy in 138 individuals with phobic fear of flying
2020, Behaviour Research and Therapy
Recent research suggests that exposure-based large-group one-session treatments (LG-OSTs) may represent useful and efficient treatment options for different types of phobic fear. Although there are effective single session- and small group-interventions for the treatment of clinically relevant Fear of Flying (FoF), no LG-OST for this type of phobic fear has been realized so far. The present study aimed to investigate feasibility and efficacy of an LG-OST for the treatment of clinically relevant FoF. Two months after an initial diagnostics to assess FoF severity and confirm the underlying diagnoses (89% specific flight phobia; 10% agoraphobia), 138 patients attended the LG-OST consisting of psychoeducation, imparting of a breathing technique and a joint 2 ½ hour exposure flight in a chartered airplane (Airbus A320). FoF again was assessed at pre- and post-treatment as well as at 6-months follow-up with the latter again containing clinical diagnostics. Only a small decrease in FoF emerged in the pre-treatment interval. From pre-to post-treatment however, substantial reductions in FoF were observed with a large mean ‘intention-to-treat’ effect size of Cohen's d = 1.42 that remained stable over time (mean d = 1.44). At follow-up, 71% of the patients were rated as fully (55%) or partially remitted (16%). Also concerning the treatment of clinically relevant FoF, a LG-OST proved feasible and effective. Therefore, LG-OST can be regarded as a highly efficient and promising treatment tool which in terms of efficiency combines the advantages of one-session individual and group treatments.
Attenuation of renewal of fear using context similarity with spider fearful individuals
2020, Learning and Motivation

Increasing in segments of 10; Wolpe, 1973). This is a widely used self-assessment fear rating scale (Bandarian-Balooch et al., 2015; Hellström & Öst, 1995; Koch et al., 2004; Öst, 1996). Psychometric properties of the SUDS ratings have been assessed and validated by Thyer, Papsdorf, Davis, and Vallecorsa (1984)); Kaplan, Smith, and Coons (1995) and Kim, Bae, and Park (2008).
The fact that renewal of fear can be due to a contextual mismatch between the exposure treatment context and the context where subsequent re-encountering occurs suggests that exposure does not completely remove the underlying fear associations. Conducting exposure in a context that is similar to the re-encounter context may be an effective method of attenuating renewal of fear. The current study examined the effects of context similarity using a single session in-vivo exposure in a sample of 61 moderate to high spider fearful first year psychology students at Griffith University (mean age was 25.36 years). Participants received standardised, in-vivo exposure with a golden orb spider. Fear was measured using self-report, behavioural avoidance, and heart rate measures. Four different contexts were utilised for this study with two being located indoors and two located outdoors. Self-reported fear ratings and heart rate showed that conducting exposure in contexts that are similar to subsequent re-encounter contexts attenuated renewal. This study shows how a simple modification to the exposure process can enhance the long-term cross contextual generalizability of exposure treatment in spider fearful individuals.
Turning negative memories around: Contingency versus devaluation techniques
2018, Journal of Behavior Therapy and Experimental Psychiatry
It is assumed that fear responses can be altered by changing the contingency between a conditioned stimulus (CS) and an unconditioned stimulus (US), or by devaluing the present mental representation of the US. The aim of the present study was to compare the efficacy of contingency- and devaluation-based intervention techniques on the diminishment in – and return of fear. We hypothesized that extinction (EXT, contingency-based) would outperform devaluation-based techniques regarding contingency measures, but that devaluation-based techniques would be most effective in reducing the mental representation of the US. Additionally, we expected that incorporations of the US during devaluation would result in less reinstatement of the US averseness.
Healthy participants received a fear conditioning paradigm followed by one of three interventions: extinction (EXT, contingency-based), imagery rescripting (ImRs, devaluation-based) or eye movement desensitization and reprocessing (EMDR, devaluation-based). A reinstatement procedure and test followed the next day.
EXT was indeed most successful in diminishing contingency-based US expectancies and skin conductance responses (SCRs), but all interventions were equally successful in reducing the averseness of the mental US representation. After reinstatement EXT showed lowest expectancies and SCRs; no differences were observed between the conditions concerning the mental US representation.
A partial reinforcement schedule was used, resulting in a vast amount of contingency unaware participants. Additionally, a non-clinical sample was used, which may limit the generalizability to clinical populations.
EXT is most effective in reducing conditioned fear responses.
