Cancer Patients' Social Relationships During 3 Years After Diagnosis-Generic and Cancer-Specific Social Networks.

BACKGROUND: Social relationships are important health resources and may be investigated as social networks. We measured cancer patients' social subnetworks divided into generic social networks (people known to the patients) and disease-specific social networks (the persons talked to about the cancer) during 3 years after diagnosis. METHOD: Newly diagnosed patients with localized breast cancer (n = 222), lymphoma (n = 102), and prostate cancer (n = 141) completed a questionnaire on their social subnetworks at 2-5 months after diagnosis and 9, 18, and 36 months thereafter. Generic and cancer-specific numbers of persons of spouse/partner; other family; close relatives, in detail; and friends were recorded as well as cancer-specific numbers of persons in acquaintances; others with cancer; work community; healthcare professionals; and religious, hobby, and civic participation. The data was analyzed with regression models. RESULTS: At study entry, most patients had a spouse/partner, all had close relatives (the younger, more often parents; and the older, more often adult children with families) and most also friends. The cancer was typically discussed with them, and often with acquaintances and other patients (74-86%). Only minor usually decreasing time trends were seen. However, the numbers of distant relatives and friends were found to strongly increase by the 9-month evaluation (P < 0.001). CONCLUSION: Cancer patients have multiple social relationships and usually talk to them about their cancer soon after diagnosis. Most temporal changes are due to the natural course of life cycle. The cancer widened the patients' social networks by including other patients and healthcare professionals and by an increased number of relatives and friends.

Alcohol use-associated alterations in the circulating metabolite profile in the general population and in individuals with major depressive disorder.

Our aim was to evaluate whether alcohol use is associated with changes in the circulating metabolite profile similar to those present in persons with depression. If so, these findings could partially explain the link between alcohol use and depression. We applied a targeted liquid chromatography mass spectrometry method to evaluate correlates between concentrations of 86 circulating metabolites and self-reported alcohol use in a cohort of the non-depressed general population (GP) (n = 247) and a cohort of individuals with major depressive disorder (MDD) (n = 99). Alcohol use was associated with alterations in circulating concentrations of metabolites in both cohorts. Our main finding was that self-reported alcohol use was negatively correlated with serum concentrations of hippuric acid in the GP cohort. In the GP cohort, consumption of six or more doses per week was associated with low hippuric acid concentrations, similar to those observed in the MDD cohort, but in these individuals it was regardless of their level of alcohol use. Reduced serum concentrations of hippuric acid suggest that already-moderate alcohol use is associated with depression-like changes in the serum levels of metabolites associated with gut microbiota and liver function; this may be one possible molecular level link between alcohol use and depression.

Negative effects in randomized controlled trials of psychotherapies and psychological interventions: A systematic review.

Background: Psychotherapy is a key evidence-based method for the treatment of mental disorders. However, little research has been published on the negative effects of psychotherapies. Aims: We examined this issue through a systematic literature review of previous systematic reviews on randomized controlled trials (RCTs). Methods: We focused on previous reviews and meta-analyses on 1) RCTs examining the effectiveness of psychotherapies and 2) previous reviews and meta-analyses specifically focusing on the negative effects of psychotherapy. We included publications published in PubMed and the Cochrane Databases from the year 2000 or later. Results: Of the 1,430 relevant publications, only a small proportion (30%) mentioned negative outcomes, mostly withdrawal. Only 57 of the extracted original studies monitored potential negative effects, and only three small-scale studies indicated negative effects. Conclusions: The systematic monitoring of negative effects in psychotherapy has not been given the same attention as has been given to the benefits of therapy.

Associations of allostatic load with sociodemographic factors, depressive symptoms, lifestyle, and health characteristics in a large general population-based sample.

OBJECTIVE: We examined the associations between allostatic load (AL) and sociodemographic factors, depressive symptoms, lifestyle and health characteristics in a population-based sample of 4993 adults in Finland. METHODS: Thirteen biomarkers were used to construct AL. High AL was defined as scoring highly in ≥4 items. RESULTS: AL scores of 4 and above were exceeded in the age group of 45-54 years in men and 65-74 years in women. Age was the strongest predictor for belonging to the high AL score group. In addition, elevated depressive symptoms (BDI-6 ≥ 4), male sex, not engaging in physical exercise, high alcohol use and a low level of education were associated with an increased likelihood of belonging to the high AL group. CONCLUSION: The older the participants were, the greater their AL burden was. However, AL burden increased more steeply as a function of age in men. In addition to lifestyle interventions, effective prevention strategies for depression at the population level could have a major public health impact in reducing the accumulation of AL burden.

The use of dental anxiety management techniques during one-session treatment: a study on five video-recorded patient cases.

OBJECTIVE: The aim was to examine what kinds of dental anxiety management techniques dentists use in the context of one-session treatment. MATERIAL AND METHODS: The data consisted of videotaped treatment sessions for five dentally anxious adults. The treatment was conducted by two experienced dentists without formal training in the treatment of dentally anxious patients or behavioral management techniques. Theory-driven qualitative content analysis, based on the anxiety management classification of Milgrom et al. was used to identify and classify the techniques used during the treatments. RESULTS: Altogether, diverse categories of dental anxiety management techniques were identified under the main themes of enhancing trust and control and psychological management. Techniques that fell into enhancing trust and control included the categories of 'building a trustful relationship', 'informational control', and 'behavioral control'. These techniques were used consistently throughout the sessions. Additionally, psychological management techniques were identified and classified as 'behavioral strategies: relaxing the body' and 'cognitive strategies: relaxing the mind', which were regularly used in specific situations. CONCLUSION: The results indicate that a variety of dental anxiety management techniques were used during one-session treatments. The findings provide valuable insights for dentists in managing their patients with dental anxiety and improving their overall treatment experience.

Do Sleep Problems Explain the Association Between Work Stress and the Trajectories of Work Ability From Midlife to Pensionable Age?

OBJECTIVE: This study examined whether mid-life work stress, defined as job strain and effort-reward imbalance (ERI), predicts work ability trajectories observed 12 years preceding the individual pensionable age. In addition, the role of sleep problems as a mediator in these associations was examined. METHODS: Survey data were collected from 2707 Finnish municipal employees. RESULTS: Identified work ability trajectories were "stable excellent," "stable good," "moderate," and "low decreasing." Baseline job strain and ERI were associated with a greater likelihood of belonging to impaired work ability trajectories when compared with "stable good" trajectory. Baseline sleep problems explained the association of job strain by 38% and of ERI by 54%. CONCLUSIONS: Mid-life work stress is associated with work ability in the last years preceding pensionable age. Sleep problems might be a potential mediator in these associations.

Occupational well-being of the work community in social and health care education during the COVID-19 pandemic-A cross-sectional study.

AIM: To evaluate factors related to the occupational well-being of social and health care educators' work communities during the COVID-19 pandemic. DESIGN: A cross-sectional study was conducted among social and health care educators in Finland 2020. METHODS: Data (n = 552) were collected through a questionnaire containing continuous, Likert scale and categorical variables. Descriptive, exploratory factor analysis and multiple regression modelling were used for analysing the data. RESULTS: Educators regarded their work as meaningful and experienced collegiality. Age and work experience were related to experiences on work community subscales and community occupational well-being. Personal occupational well-being and activities promoting occupational well-being on the community level were most related to experiences of the work community and its well-being. The activities that promote occupational well-being on the work community level should be emphasized.

Serum levels of carnosine may be associated with the duration of MDD episodes.

BACKGROUND: Major depressive disorder (MDD) is a recurrent disorder that incurs a high societal burden. However, the etiology of MDD remains unclear. The functioning of several systems associated with the etiopathogenesis of MDD, such as inflammatory and stress systems, is partially modulated by the dipeptide carnosine. METHODS: The study comprised 99 MDD patients and 253 non-depressed controls aged 20-71 years. Fasting serum samples were analyzed using ultra-performance liquid chromatography coupled to mass spectrometry to determine the serum levels of carnosine and its constituent, histidine. We compared these metabolites in three different settings: 1) MDD patients vs. non-depressed controls and 2) remitted vs. non-remitted MDD patients, as well as 3) changes in the metabolite levels during the follow-up period within a) the remitted group and b) the non-remitted group. In addition, we assessed the possible effect of medications on the measured metabolites. RESULTS: We observed higher serum levels of carnosine in the MDD group compared to the control group at baseline (OR = 1.895, 95%CI = 1.223-2.937, p = 0.004). Elevated serum levels of carnosine were also associated with a longer duration of the depressive episode (Z = 0.406, p = 0.001). However, the use of any antipsychotic medication (n = 36) was associated with lowered carnosine levels (p = 0.010 for use vs. non-use). At the follow-up, remitted and non-remitted participants displayed no significant differences in their carnosine levels (Z = -0.14, p = 0.891) or histidine (Z = -1.39 p = 0.164). CONCLUSIONS: An increase in circulating carnosine may characterize depressive episodes and may represent a protective homeostatic reaction against MDD-related oxidative stress and inflammation.

The effectiveness of a diagnostic interview and modified one-session treatment for dental anxiety in primary dental care-A pilot study.

AIMS: To investigate the effectiveness of a cognitive-behavioral intervention that included either a diagnostic interview (DI) or a DI combined with modified one-session treatment (M-OST) for dental anxiety among adults in a primary care setting. METHODS AND RESULTS: Nineteen participants were assigned to either a DI before conventional dental treatment (group T1) or DI and M-OST (group T2). The severity of dental anxiety was measured with three self-reported measures before and after the intervention: the Modified Dental Anxiety Scale (MDAS), the Index of Dental Anxiety and Fear (IDAF-4C), and the Visual Analogue Scale-Anxiety (VAS-A). Dental care attendance was enquired in a 1-year follow-up. The scores for all three scales decreased among both study groups, with the largest decrease recorded in treatment group T1 assessed with the VAS-A. A higher dental anxiety score measured before the intervention associated most significantly with a higher dental anxiety score after the intervention. At the 1-year follow-up, 82% of participants in T1 and 67% in T2 had visited a dentist. CONCLUSION: A DI alone and combined with M-OST is potentially effective in reducing dental anxiety and in supporting the engagement of adult patients with dental treatment in primary dental care.

Fear, isolation and the importance of support: A qualitative study of parents' experiences of feeding a child born with esophageal atresia.

OBJECTIVE: Feeding and swallowing difficulties in children are increasing due to improved survival rates of children with complex medical conditions. Despite being common complications of esophageal atresia (EA), EA related feeding difficulties have received little attention in research. Establishing positive feeding interactions and practices are important for child health and development, and for parental and child mental health. The current study aimed to investigate the parental experiences of feeding a child born with EA. METHODS: An international online survey was developed and disseminated to parents of children born with EA, aged 0-12 years, in collaboration with a patient charity for EA. Reflexive Thematic Analysis was used to analyze the qualitative survey responses. RESULTS: 176 participants were included in the qualitative sample from a larger international online survey study, chosen by a process of selective coding. Three themes were constructed during the analysis: 1) Anxiety, trauma and loss; 2) Isolated and unsupported; and 3) Supported. The results indicated that parents of children born with EA experienced significant anxiety related to their child's swallowing and feeding difficulties and traumatic experiences during feeding, and that these led to parents feeling a sense of loss and sadness. It was also found that support, or a lack of support, within parents' social environment might mediate parental experiences of child's feeding difficulties. CONCLUSIONS: This study highlighted the importance of support for parents of children born with EA, and suggested a need for improved guidance for feeding and swallowing difficulties.

Association between alexithymia and substance use: A systematic review and meta-analysis.

Alexithymia has been associated with substance use, but the magnitude of the association has not been evaluated and sub-group differences, if any, are unknown. The aim of this meta-analysis is to systematically review the association between alexithymia and substance use (alcohol or illicit drugs). We identified studies through a systematic review of PubMed and Web of Science and obtained a total of 52 publications using the Toronto Alexithymia Scale-20 scale. Random effects meta-analysis was used to evaluate the overall and sub-group associations. Of the studies, 50 were cross-sectional and two longitudinal. Alexithymia was associated with any substance use (Cohen's d = 0.62, 95% confidence interval [CI] 0.49-0.76), with little difference between estimates for use of alcohol or illicit drugs. A stronger association was observed for the alexithymia dimension "Difficulty in Identifying Feelings" (d = 0.64, 95% CI = 0.47-0.81) and "Difficulty in Describing Feelings" (d = 0.44, 95% CI = 0.32-0.55) than for "Externally Oriented Thinking" (d = 0.19, 95% CI = 0.09-0.28). The association was stronger in studies with clinical patient populations (d = 0.83, 95% CI = 0.62-1.05) than in those investigating general or student populations, and in studies with a majority of male rather than female participants. These findings suggest a strong overall association between alexithymia and substance use and a very strong association among clinical patient populations. The association may be stronger with the emotion-related dimensions than with the cognition-related dimension of alexithymia. As nearly all the studies were cross-sectional, more longitudinal studies are needed.

Psychiatric Symptoms, Posttraumatic Growth, and Life Satisfaction Among Parents of Seriously Ill Infants: A Prospective Case-Controlled Study.

We evaluated psychiatric symptoms, posttraumatic growth, and life satisfaction among the parents (n = 34) of newborns (n = 17) requiring therapeutic hypothermia or urgent surgery (interest group). Our control group included 60 parents of healthy newborns (n = 30). The first surveys were completed soon after diagnosis or delivery and the follow-up surveys 1 year later (participation rate 88% in the interest group and 70% in the control group). General stress was common in both groups but was more prevalent in the interest group as were depressive symptoms, too. Anxiety was more common in the interest group, although it showed a decrease from the baseline in both groups. Life satisfaction had an inverse correlation with all measures of psychiatric symptoms, and it was lower in the interest group in the early stage, but similar at 12 months due to the slight decline in the control group. Mothers in the interest group had more anxiety and depressive symptoms than fathers in the early stage. Mothers had more traumatic distress than fathers at both time points. Half of the parents experienced substantial posttraumatic growth at 12 months. In conclusion, the serious illness of an infant substantially affects the well-being of the parents in the early stages of illness and one year after the illness.

The association between chronotype and sleep quality among female home care workers performing shift work.

There is a scarcity of evidence on the association between shift work, sleeping parameters, heart rate variability (HRV), and chronotype, i.e., morningness and eveningness. The aims of this study were to 1) compare participants with different chronotypes (morning (M), evening (E), or neither (N)) in terms of their total sleep time, sleep efficiency, and HRV parameters, taking their age into account, and 2) examine whether self-reported work-related stress, the length of the working career and years performing shift work affect this association. The participants of the study were home care workers working in two shifts in one municipality in Eastern Finland (N = 395). Of these, 52 females (mean age 42.78 y, SD 12.92 y) completed the study questionnaire and participated in physiological measurements. Several sleep-related parameters were assessed (total sleep time, sleep efficiency, number of awakenings, and length of awakening) and indices of autonomic nervous system based on HRV were calculated. The participants worked in two shifts: a morning shift (7:00-15:00 h) and an evening shift (14:00-21:30 h). All these parameters were assessed during the night before the first work shift (N1), the night before the second work shift (N2), the night before the final work shift (N3), and the night before the first day off work (N4). According to the results, 21.2% of the participants were M-types, 17.3% were E-types, and 61.5% were N-types. On average, the participants had been in working life for 18.8 years and performing shift work for 13.7 years. On night N3, E-types had a significantly shorter total sleep time and spent less time in bed compared to M- and N-types. The total sleep time of M-type and N-type participants was on average 66 minutes and 82 minutes longer, respectively, when compared to E-types on night N3. There were no statistically significant differences in actigraphy-based sleep quality parameters between M-, N-, and E-types on nights N1, N2, and N4. Our results together indicate that M- and N-type individuals may have better sleep quality than E-types, which was also reflected in HRV parameters. Further research with longitudinal study design and workplace interventions is needed to determine how the chronotype can be optimally and individually utilized to improve the health and well-being of morning-type and evening-type people. This is particularly important for both younger and older workers entering the workforce to support healthier and longer working lives.

Children's Disclosures of Physical Abuse in a Population-Based Sample.

Few studies have explored the disclosure of child physical abuse although child sexual abuse disclosure has been widely studied and debated for years. The present study explores the characteristics of child physical abuse disclosures and compares them to previously published findings on child sexual abuse disclosure from the same data. The data consist of a representative sample of 11,364 sixth and ninth graders. Participants responded to a wide variety of questions concerning experiences of violence, including child physical abuse and child sexual abuse, in the Finnish Child Victim Survey conducted in 2013. Within this sample, the prevalence of child physical abuse was 4.1%. Children reporting abuse experiences also responded to questions regarding disclosure, reactions encountered during disclosure, and potential reasons for nondisclosure. Findings show that most of the children who disclosed physical violence had disclosed to their mother. The overall disclosure rate of child physical abuse was 74%. However, only 42% had disclosed to adults, and even fewer had reported their experiences to authorities (12%). The most common reason for nondisclosure was that the youth did not consider the experience sufficiently serious to report (53%). These findings were largely in line with the child sexual abuse disclosure rates in our previous study. Analyses of variables associated with disclosing to an adult indicate that the strongest factors predicting disclosure to an adult are younger age, female gender, no previous experiences of child physical abuse, and parents knowing who their child spends her or his spare time with. Implications for further research and practice are discussed.

Work community factors, occupational well-being and work ability in home care: A structural equation modelling.

AIM: To examine how work community factors are related to occupational well-being and work ability, and how occupational well-being is related to work ability. DESIGN: A cross-sectional study was conducted among home care workers in one municipality in Finland. METHODS: A self-administered survey on work and well-being was filled out by 167 employees working two shifts in 2019. Structural equation modelling was used to analyse the association between work community factors, occupational well-being and work ability. RESULTS: The only work community factor directly affecting Occupational well-being was Information and work organization; the effect of the other two factors, Social support and Influence on work shifts, was indirect. All work community factors indirectly affected Work ability. Home care should emphasize information provision and work organization with optimal time use. This requires social support, a well-functioning work atmosphere and providing employees with opportunities for influence and participation.

Heart rate variability and chronotype - a systematic review.

There is a scarcity of evidence on the association between heart rate variability (HRV) and chronotype, i.e., morningness and eveningness. The aim of this systematic review was to examine the association between chronotype, HRV, mood and stress response. We searched PubMed, Web of Science, Scopus, Cinahl, PsycINFO and Google Scholar for peer-reviewed articles published in English between January 2000 and June 2020. A total of 11 articles met the inclusion criteria and were on study population, assessment of HRV and chronotype, main results and study limitations. Seven of the included studies were experimental and four were crossovers. The sample size varied from 9 to 221 participants, and both females and males were included. HRV was assessed using mostly time-domain and frequency-domain parameters; nonlinear parameters were used in only one study. The most used assessments for measuring chronotype were the Horne-Östberg Morningness-Eveningness Questionnaire (MEQ) and the Munich Chronotype Questionnaire (MCTQ). The results showed that chronotype was associated with HRV, but the study designs were situation-specific, focusing, for example, on the effects of shiftwork, stressful situations, exercise, or sleep deprivation on HRV. In addition, some studies showed that evening types (E-type) performed better during evening or nighttime tasks, whereas morning types (M-type) performed better during morning activities. Specifically, E-types showed decreased HRV and HRV recovery in relation to tasks performed during morning or daytime when compared to M-types. As the findings are somewhat contradictory and include some methodological limitations (e.g., small sample sizes, age groups), it is important for future studies to evaluate the association between chronotype and HRV in a longitudinal setting. In addition, further research is needed to determine how chronotype can be optimally and individually utilized to increase the health and well-being of M-type and E-type individuals.

Resilience and health-related quality of life in patients with pulmonary diseases receiving ambulatory oxygen therapy.

BACKGROUND: Pulmonary diseases affect health-related quality of life (HRQoL), but there are few data on patients' adaptation to a serious illness. This study assessed resilience and its associations with HRQoL, life satisfaction, anxiety and depression in patients with pulmonary diseases receiving ambulatory oxygen therapy. METHODS: In this prospective cohort study, we enrolled 42 patients with pulmonary diseases receiving ambulatory oxygen therapy. The patients completed the following questionnaires at baseline and after one and three months; the Resilience Scale-25, the Life Satisfaction Scale-4, the 15D instrument of HRQoL, the Hospital Anxiety and Depression Scale (HADS) and the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0). To compare HRQoL, we recruited age- and gender-matched controls from the general population (n = 3574). The primary outcome was the proportion of patients with low resilience. RESULTS: Half (42-48%) of the patients had low resilience, which was correlated with low HRQoL, low levels of life satisfaction and higher levels of anxiety and depression. Patients had very low HRQoL compared to controls. Dissatisfaction with life increased during the 3-months follow-up, but only a few patients had anxiety or depression. Patient satisfaction with assistive technology was high; the median QUEST 2.0 score (scale 1-5) was 4.00 at baseline, 3.92 at one month and 3.88 at three months. CONCLUSIONS: Resilience was low in half of the patients with pulmonary diseases receiving ambulatory oxygen therapy. Higher resilience was positively correlated with HRQoL and life satisfaction and negatively correlated with anxiety and depression. TRIAL REGISTRATION: ClinicalTrials.gov Protocol Record 507A023.

Anxiety and Depression in Parents of Children Born with Esophageal Atresia: An International Online Survey Study.

PURPOSE: Caring for a chronically ill child can be stressful and requires additional care from parents. Parental mental health and stress may impact both parental and child wellbeing, leading to maladaptive parenting practices, and interference with illness management. The aim of the study was to explore the levels of anxiety and depression in parents of children born with esophageal atresia (EA) and to investigate whether parental anxiety and depression were associated with child's medical characteristics or with parental factors. DESIGN AND METHODS: An international online survey was developed and disseminated to parents of children born with EA, aged 0-12 years, via EA patient charity social network sites. A one-way between subjects ANOVA and post hoc statistical analyses were used to examine differences in mean scores of parental anxiety and depression between sub-groups that described child's medical characteristics and parental characteristics. RESULTS: A total of 240 parents completed the survey from 17 different countries. Of these, nearly 70% self-reported raised levels of anxiety, whilst 38% self-reported raised levels of depression. Statistically significant differences in mean scores of parental anxiety and depression were found between sub-groups that described the child's feeding problems, parental age, and perceived support for caring, caring stress and money matters. CONCLUSION: Child's feeding problems related to esophageal atresia, and parental factors, such as younger age, perceived lack of support for caring, caring stress, and money worries, may contribute to the increased levels of parental anxiety and depression in parents of children born with EA.

Comparison of the level of allostatic load between patients with major depression and the general population.

OBJECTIVE: We compared the level of allostatic load (AL) between patients with major depressive disorder (MDD) and non-depressed controls using two definitions of AL: continuous AL scores (AL index) and clinically significant high AL (≥4). We examined whether MDD was associated with AL independent of basic socioeconomic (age, sex, cohabiting status and level of education) and lifestyle factors (smoking and alcohol use). METHODS: The MDD patient sample consisted of 177 psychiatric outpatients (mean age 33.7, SD 10.7 years), who were recruited from the Department of Psychiatry at Kuopio University Hospital, Finland, in 2016-19. The non-depressed controls (n = 228, mean age 49.8, SD 10.1 years) lived in the municipality of Lapinlahti, Finland. Ten biomarkers were used to construct the two AL variables. These indicators were systolic and diastolic blood pressure, total cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, glucose, creatinine, waist circumference, body mass index (BMI) and C-reactive protein (CRP). RESULTS: The mean AL scores did not significantly differ between MDD patients (2.97) and non-depressed controls (3.12), thus it was not associated with MDD in univariate analysis. In multivariate models a higher AL index was associated with a 1.42 to 1.82 times higher likelihood of belonging to the MDD group. Furthermore, we found that high AL (i.e. AL ≥ 4) was associated with MDD, with the likelihood ranging between 2.27 and 2.96 compared with the non-depressed controls in multivariate models. CONCLUSIONS: Even young adult patients with MDD appear to display clinically significant, high AL compared with non-depressed controls. Thus, it is important to pay attention to the somatic health of depressed patients in addition to their mental health.

Patients' multifaceted views of dental fear in a diagnostic interview.

OBJECTIVES: The aim was to examine how patients describe and perceive their dental fear (DF) in diagnostic interviews. MATERIAL AND METHODS: The sample consisted of dentally anxious patients according to the Modified Dental Anxiety Scale (MDAS), who had problems coping with conventional dental treatment. The voluntary participants (n = 7, aged 31-62 years) attended a diagnostic interview aiming to map their DF before dental treatment. The data were analysed by theory-driven qualitative content analysis. The themes consisted of the four components of DF: emotional, behavioural, cognitional, and physiological, derived from the Index of Dental Anxiety and Fear. RESULTS: Within these four themes, treated as the main categories, 27 additional categories related to the patients' interpretations of DF were identified in three contexts: before, during and after dental treatment. 10 categories depicted difficult, uncontrollable, or ambivalent emotions; nine depicted behavioural patterns, strategies, or means; five depicted disturbing, strong, or long-lasting physiological reactions, including panic and anxiety symptoms. The remaining three categories related to cognitive components. CONCLUSIONS: The results indicate that dental care professionals may gain comprehensive information about their patients' DF by means of four component-based diagnostic interviews. This helps them to better identify and encounter patients in need of fear-sensitive dental care. TRIAL REGISTRATION NUMBER: NCT02919241.
