AB  - People resort to various questionable health practices to preserve or regain health - they intentionally do not adhere to medical recommendations (e.g. self-medicate or modify the prescribed therapies; iNAR), or use traditional/complementary/alternative (TCAM) medicine. As retrospective reports overestimate adherence and sufer from recall and desirability bias, we tracked the variations in daily questionable health behaviors and compared them to their retrospectively reported lifetime use. We also preregistered and explored their relations to a wide set of psychological predictors - distal (personality traits and basic thinking dispositions) and proximal (diferent unfounded beliefs and biases grouped under the term irrational mindset). A community sample (N = 224) tracked daily engagement in iNAR and TCAM use for 14 days, resulting in 3136 data points. We observed a high rate of questionable health practices over the 14 days; daily engagement rates roughly corresponded to lifetime ones. Both iNAR and TCAM were weakly, but robustly positively related. Independent of the assessment method, an irrational mindset was the most important predictor of TCAM use. For iNAR, however, psychological predictors emerged as relevant only when assessed retrospectively. Our study ofers insight into questionable health behaviors from both a within and between-person perspective and highlights the importance of their psychological roots.

AB  - Objectives We aimed to (1) develop a novel instrument, suitable for the general population, capturing intentional non-adherence (iNAR), consisting of non-adherence to prescribed therapy, self-medication and avoidance of seeking medical treatment; (2) differentiate it from other forms of non-adherence, for example, smoking; and (3) relate iNAR to patient-related factors, such as sociodemographics, health status and endorsement of irrational beliefs (conspiratorial thinking and superstitions) and to healthcare-related beliefs and experiences ((mis)trust and negative experiences with the healthcare system, normalisation of patient passivity).

Design То generate iNAR items, we employed a focus group with medical doctors, supplemented it with a literature search and invited a public health expert to refine it further. We examined the internal structure and predictors of iNAR in an observational study.

Setting Data were collected online using snowball sampling and social networks.

Participants After excluding those who failed one or more out of three attention checks, the final sample size was n=583 adult Serbian citizens, 74.4% female, mean age 39.01 years (SD=12.10).

Primary and secondary outcome measures The primary, planned outcome is the iNAR Questionnaire, while smoking was used for comparison purposes.

Results Factor analysis yielded a one-factor solution, and the final 12-item iNAR Questionnaire had satisfactory internal reliability (alpha=0.72). Health condition and healthcare-related variables accounted for 14% of the variance of iNAR behaviours, whereas sociodemographics and irrational beliefs did not additionally contribute.

Conclusions We constructed a brief yet comprehensive measure of iNAR behaviours and related them to health and sociodemographic variables and irrational beliefs. The findings suggest that public health interventions should attempt to improve patients' experiences with the system and build trust with their healthcare practitioners rather than aim at specific demographic groups or at correcting patients’ unfounded beliefs.

AB  - The vast majority of studies investigating personality structure is done using adult samples. If 
personality is assessed in children, parental ratings are preferably used method, while self reports are seldom used. Here we use self-report measures to study the developmental 
stability of the seven-factor personality structure defined by the HEXACO model and 
Disintegration trait. We focus on middle childhood children, young teens, and teenagers. 
Sample consisted of four groups: 1) age 10-11 (N=164, 49.4% female), 2) age 12-13 (N=195, 
48.9% female), 3) age 14-16 (N=319, 59.2% female), 4) age 17-18 (N=201, 49.5% female). 
Data were collected in several elementary and high schools in Serbia and Montenegro. 
Personality traits were assessed using 60 items HEXACO, and 20 items DELTA 
questionnaires. The stability of the seven-factor personality structure was tested using 
orthogonal procrustes rotations, and the analysis was done on facets of all seven personality 
traits. Congruence coefficients and factor loadings were calculated for all facets for all six 
pairwise comparisons. Overall, the average congruence of factors ranged between .69 
(Emotionality) and .96 (Disintegration). The average congruence of facets ranged between 
.41 (Sincerity) and .95 (Sentimentality), with the majority of facets having average 
congruence above .85. Average factor loadings for Disintegration range between .55 (Depression) and .85 (Perceptual Distortions), for Honesty between .20 (Sincerity) and .39 
(Greed avoidance), for Emotionality between .19 (Anxiety) and .53 (Sentimentality), for 
Extraversion between .34 (Sociability), and .47 (Social self-esteem and Liveliness), for 
Agreeableness .34 (Patience), and .54 (Flexibility), for Conscientiousness .33 (Organization) 
and .53 (Diligence), and for Openness .53 (Creativity) and .67 (Inquisitiveness). As expected, 
personality structure is least stable in the first age group but stabilizes in groups 3 and 4. We 
discuss, in detail, stability and content of personality factors on different age groups, and 
practical implications on assessment these results have.
