Since its inception, Methodology, the official organ of the European Association of Methodology, has been an online journal with a strong European vocation and dedication ‘‘to promote research and the development of empirical research methods in the fields of behavioral, social, educational, health and economic sciences, as well as in the field of evaluation research." Methodology publishes the original contributions of researchers from all over the world in the form of research articles, software information, and instructional papers.

Forty-four studies (published between 1920 and 2013) with data on 963 anxiety disordered patients and 1,222 control subjects were obtained through PubMed and PsycINFO, as well as from a previous meta-analysis on fear conditioning (Lissek et al.). Results demonstrated robustly increased fear responses to conditioned safety cues (CS-) in anxiety patients compared to controls during acquisition. This effect may represent an impaired ability to inhibit fear in the presence of safety cues (CS-) and/or may signify an increased tendency in anxiety disordered patients to generalize fear responses to safe stimuli resembling the conditioned danger cue (CS+). In contrast, during extinction, patients show stronger fear responses to the CS+ and a trend toward increased discrimination learning (differentiation between the CS+ and CS-) compared to controls, indicating delayed and/or reduced extinction of fear in anxiety patients. Finally, none of the included study characteristics, such as the type of fear measure (subjective vs. psychophysiological index of fear), could account significantly for the variance in effect sizes across studies. Further research is needed to investigate the predictive value of fear extinction on treatment outcome, as extinction processes are thought to underlie the beneficial effects of exposure treatment in anxiety disorders.

Research paper thumbnail of Couples dealing with multiple sclerosis: a diary study examining the effects of spousal interactions on well-being

In addition to addressing the physical disability caused by MS, both patients and their partners must find ways to deal with the uncertainty of the disease's progression, changing role responsibilities and the psychosocial consequences. Being involved in a supportive relationship is believed to play a key role in adjustment to stressful life events such as chronic illness. Ample research has shown that the global perception that support is available when it is needed is related to greater psychological and physical well-being. However, results are less consistent when the effects of actual support or enacted support are studied. Some studies have documented positive effects, whereas others have shown neutral effects, or negative effects. These inconsistent results suggest that the effects of spousal interactions are not the same for each person, or that they depend on other factors that may interact with spousal interactions to determine its effect. This thesis considers daily supportive interactions with the partner among couples dealing with MS. The study is centred around two main issues: (1) The amount of support received and provided by both patients and partners. Interactions with the partners may change when one partner has a chronic illness. Partners are likely to provide more support and help to their partner, and receive less support in return. (2) The costs and benefits of received and provided support for patient's and partner's well-being. Both partners of 61 couples dealing with MS completed diaries for fourteen days and filled out questionnaires prior to completing the diaries and at seven months follow-up. Besides the diary method, other important features of the study were that both patients and partners were examined as receivers and providers of support and that we distinguished between emotional, instrumental and negative interactions. Further, specific attention was given to differences between patients and partners, both in the amount of support that was given and received as well as the relation between supportive interactions and well-being. Additionally, it was examined whether patients and partners perceived their relationship as imbalanced and whether this effected their well-being. It was shown that instrumental interactions between patients and partners were imbalanced; patients reported providing less instrumental support than partners. However, patients and partners provided equal amounts of emotional support. Overall not much support was found for the costs of receiving or providing emotional or instrumental support. In contrast, the results underscribe the importance of emotional support for both patient's and partner's well-being. Additionally, both patients and partners benefited from providing instrumental support. Negative responses received from the partner were negatively related to patient's and partner's end-of-day well-being, however, this effect was not as potent as we expected based on previous studies and this effect was moderated by the receipt of emotional support. Finally, the results showed that when patients were more disabled, patients and partners may perceive their relationship as imbalanced, which has negative consequences for the level of depression of both.

Samples were collected in seven different countries. The results are based on 13,226 parent ratings and 8893 teacher ratings. The adequacy of fit for the cross-informant model was established on the basis of three approaches: conventional rules of fit, simulation, and comparison with other models. The results indicated that the cross-informant model fits these data poorly. These results were consistent across countries, informants, and both clinical and population samples. Since inadequate empirical support for the cross-informant syndromes and their differentiation was found, the construct validity of these syndrome dimensions is questioned.
