Assessing the Factorial Validity of the Attitudes and Belief Scale 2-Abbreviated Version: A Call for the Development a Gold Standard Method of Measuring Rational and Irrational Beliefs

Rational Emotive Behaviour Therapy (REBT) does not possess a measure of rational and irrational beliefs that meets internationally recognised standards for acceptable psychometric properties. Without such a measure the theory/practice of REBT cannot be rigorously evaluated, thus undermining its scientific veracity. The current study investigates the validity and reliability of a recently developed measure of rational and irrational beliefs: the Attitudes and Belief Scale 2-Abbreviated Version (ABS-2-AV). University students from three countries completed the ABS-2-AV (N = 397). An alternative models framework using confirmatory factor analysis indicated that a theoretically consistent eight-factor model of the ABS-2-AV provided the best fit of the data. A number of post-hoc modifications were required in order to achieve acceptable model fit results, and these modifications revealed important methodological limitations with the ABS-2-AV. Results indicated that the validity of the ABS-2-AV was undermined due to items measuring both the psychological process of interest (rational and irrational beliefs) and the context in which these beliefs processes are presented. This is a serious methodological limitation of the ABS-2 and all questionnaires derived from it, including the ABS-2-AV. This methodological limitation resulted in the ABS-2-AV possessing poor internal reliability. These limitations are discussed in relation to the broader REBT literature and the impact such problems have on research and practice. A call is made for REBT researchers to come together to develop a “gold standard” method of assessing rational and irrational beliefs that meets international standard for psychometric excellence

Response of wild bee diversity, abundance, and functional traits to vineyard inter-row management intensity and landscape diversity across Europe

Agricultural intensification is a major driver of wild bee decline. Vineyards may be inhabited by plant and animal species, especially when the inter-row space is vegetated with spontaneous vegetation or cover crops. Wild bees depend on floral resources and suitable nesting sites which may be found in vineyard inter-rows or in viticultural landscapes. Inter-row vegetation is managed by mulching, tillage, and/or herbicide application and results in habitat degradation when applied intensively. Here, we hypothesize that lower vegetation management intensities, higher floral resources, and landscape diversity affect wild bee diversity and abundance dependent on their functional traits. We sampled wild bees semi-quantitatively in 63 vineyards representing different vegetation management intensities across Europe in 2016. A proxy for floral resource availability was based on visual flower cover estimations. Management intensity was assessed by vegetation cover (%) twice a year per vineyard. The Shannon Landscape Diversity Index was used as a proxy for landscape diversity within a 750 m radius around each vineyard center point. Wild bee communities were clustered by country. At the country level, between 20 and 64 wild bee species were identified. Increased floral resource availability and extensive vegetation management both affected wild bee diversity and abundance in vineyards strongly positively. Increased landscape diversity had a small positive effect on wild bee diversity but compensated for the negative effect of low floral resource availability by increasing eusocial bee abundance. We conclude that wild bee diversity and abundance in vineyards is efficiently promoted by increasing floral resources and reducing vegetation management frequency. High landscape diversity further compensates for low floral resources in vineyards and increases pollinating insect abundance in viticulture landscapes.AustrianScienceFund,Grant/AwardNumber:I2044-B25;BundesministeriumfürBildungundForschung;UnitateaExecutivapentruFinantareaInvatamantuluiSuperior,aCercetarii,DezvoltariisiInovarii;MinisteriodeEconomíayCompetitividad;AgenceNationaledelaRecherchePeer Reviewe

The brown marmorated stink bug, Halyomorpha halys

Halyomorpha halys, commonly known as the brown marmorated stink bug, has been recorded for the first time from the Maltese Islands. The record is currently based on the capture of a single specimen. Information is provided on the distribution range of this polyphagous species which was accidentally introduced into Europe (Switzerland) in 2007 and since then has invaded many European countries. Morphological details are also included to aid in the discrimination of this species from similar species occurring in the Mediterranean region. Notes are provided on the feeding strategies used by this insect and the type of damage incurred on agricultural commodities, which are often rendered unsaleable.peer-reviewe

Cognitive evolutionary therapy versus standard cognitive therapy for depression:A single-blinded randomized clinical trial

OBJECTIVE: To compare the efficacy of cognitive evolutionary therapy (CET) with cognitive therapy (CT) for depression.METHODS: Ninety-seven participants (78 females/19 males) were randomized to a single-blinded controlled trial (CET: n = 51 vs. CT: n = 46). Assessments were conducted at baseline, Sessions 4 and 8, posttreatment, and 3-month follow-up. Clinical diagnoses were made with Structured Clinical Interview for DSM-IV (SCID) and self-reports for depression and secondary outcomes.RESULTS: Although both groups showed significant reductions in depressive symptomatology, the overall Time × Treatment group interaction in the intent to treat analysis was not significant (p = .770, posttreatment: d = 0.39). However, CET was superior to CT at increasing engagement in social and enjoyable activities (p = .040, posttreatment: d = 0.83, p = .040) and showed greater reductions than the CT group in behavioral inhibition/avoidance (p = .047, d = 0.62). The between-group differences generally diminished at the 3-month follow-up.CONCLUSIONS: CET is a novel therapy for depression that may add therapeutic benefits beyond those of CT.</p
