Type Headache

We validated a German-language self-administered headache questionnaire for migraine (M), tension-type headache (TTH) and trigeminal autonomic cephalalgia (TAC) in a general population sample of people with headache. Randomly selected subjects ( n = 240) diagnosed by the questionnaire as M ( n = 60), TTH ( n = 60), a combination of M and TTH (M+TTH, n = 60) and TAC ( n = 60) were invited for examination by headache specialists. One hundred and ninety-three subjects (80%) were studied. Sensitivity and specificity for M were 0.85 and 0.85, for TTH 0.6 and 0.88, for M+TTH 0.82 and 0.87, respectively. Cohen's κ was 0.6 (95% confidence interval 0.50, 0.71). Of 45 patients with TAC according to the questionnaire, physicians diagnosed cluster headache in two patients only. We conclude: (i) the questionnaire can be used to diagnose M, TTH and M+TTH, but not TAC; (ii) screening questionnaires for epidemiological research should be validated in a general population sample but not in a tertiary headache clinic.

Few Data

OBJECTIVE: To analyze the demographic features of the population sample, the time of headache complaint until first consultation and the diagnosis of primary and secondary headaches. METHOD: 3328 patients were analyzed retrospectively and divided according to gender, age, race, school instruction, onset of headache until first consultation and diagnosis(ICHD-II, 2004). RESULTS: Sex ratio (Female/Male) was 4:1, and the mean age was 40.7±15 years, without statistical differences between sexes. Approximately 65% of the patients were white and 55% had less than eight years of school instruction. Headache complaint until first consultation ranged from 1 to 5 years in 32.99% patients. The most prevalent diagnosis were migraine (37.98%), tension-type headache-TTH (22.65%) and cluster headache (2.73%). CONCLUSION: There are few data on epidemiological features of headache clinic populations, mainly in developing countries. According to the literature, migraine was more frequent than TTH. It is noteworthy the low school instruction of this sample and time patient spent to seek for specialized attention. Hypnic headache syndrome was seen with an unusual frequency.

Cluster Approach

Prototypes of personality were investigated in two studies. In study I, clusters of Big‐Five‐based prototypes were examined using a general population sample of 1908 German adults. Convergent evidence suggested the appropriateness of a five‐cluster solution, which corresponds to previously identified temperament based prototypes. In study II, the five‐cluster solution was cross‐validated in a sample of 256 prisoners. Moreover, it was shown that a population‐based approach (using discriminant functions derived from study I) was superior over the traditional sample‐based cluster approach (using Ward followed by k‐means). The authors argue that future typological research can be sufficiently grounded on a five‐prototype conception rather than on a three‐prototype conception, and suggest a new and flexible assignment procedure.

ObjectiveTo analyse 12-month response to GH treatment in a single-country cohort of hypopituitary adult patients with GH deficiency (GHD) in regards to health-related quality of life (HRQoL) and insulin-like growth factor-1 (IGF-1) compared with values from general population sample. Moreover, association between the response in HRQoL and the IGF-1 values in patients and in the background population was investigated.DesignHRQoL was assessed by quality of life assessment of GH deficiency in adults (QoL-AGHDA) in 651 patients retrieved from the German KIMS (Pfizer International Metabolic Database) before and after 12 months of GH replacement and in a sample drawn from a cross-sectional study in Germany (n=2734). IGF-1 was measured in KIMS patients and in the population-based study with the same assay technique.ResultsIn KIMS patients, mean QoL-AGHDA scores before GH replacement were 9.2±6.8 (8.7±6.8) in women (men) and in the general population sample 4.5±5.3 (4.3±5.0) in women (men). Mean differences in QoL-AGHDA scores were statistically significant for all age categories (P<0.05). The mean IGF-1 SDS of KIMS patients before GH replacement was −1.1±1.4 (−0.8±1.4) in women (men). After GH replacement, a significant increase of IGF-1 concentration and a significant decrease of QoL-AGHDA scores near to age- and gender-specific population-based values were observed.ConclusionsThis study confirms an improvement in HRQoL and an increase of IGF-1 SDS in GH-replaced adults, which approximated the values of general population. However, there was no association between IGF-1 values and HRQoL assessment as one of the important treatment outcomes.

Prevalence Ratios

The aim of this study was to estimate the prevalence of primary headaches in pre-adolescent children, as well as headache frequency and days of treatment in this population. Sample consisted of 1994 children (aged 5–12 years). Parents were interviewed by a paediatric headache specialist using a questionnaire that allowed the classification of headaches using the criteria of the Second Edition of the International Classification of Headache Disorders. The most severe headache type was classified (mutually-exclusive diagnoses). Prevalence and prevalence ratios were calculated overall, as well as by age, gender and race. The overall prevalence of migraine was 3.76%, non-significantly higher in boys (3.9%) than in girls (3.6%). Prevalence of probable migraine was significantly higher than the prevalence of migraine for all ages (overall prevalence of 17.1%). Chronic migraine (CM) happened in 0.8% (girls, 1.15%; boys, 0.5%). Infrequent episodic tension-type headache (ETTH) happened in 2.3% of the sample while prevalence of frequent ETTH was 1.6%. Probable TTH happened in 13.5%. Most children with migraine had consulted a medical doctor because of their headaches, and the proportion was higher among children with CM (93.7%). Prevalence of primary headaches is high in young children. Probable diagnoses are more common than full diagnoses. Consultation rates are elevated.

Hypothesis Evaluation

We investigate in-service teachers’ reasons for trust and distrust in educational research compared to research in general. Building on previous research on a so-called “smart but evil” stereotype regarding educational researchers, three sets of confirmatory hypotheses were preregistered. First, we expected that teachers would emphasize expertise—as compared with benevolence and integrity—as a stronger reason for trust in educational researchers. Moreover, we expected that this pattern would not only apply to educational researchers, but that it would generalize to researchers in general. Furthermore, we hypothesized that the pattern could also be found in the general population. Following a pilot study aiming to establish the validity of our measures (German general population sample; N = 504), hypotheses were tested in an online study with N = 414 randomly sampled German in-service teachers. Using the Bayesian informative hypothesis evaluation framework, we found empirical support for five of our six preregistered hypotheses.

The 2D: 4D digit ratio, the ratio of the length of the second finger to the length of the fourth finger, is often considered a proxy for testosterone exposure in utero. A recent study reported, among other things, an association between the left-hand 2D:4D and self-employment in a sample of 974 adults. In this preregistered study, we replicate the 2D:4D results on a sample of more than 2100 adults from the German Socioeconomic Panel-Innovation Sample (SOEP-IS). We find no statistically significant associations between 2D:4D and self-employment.
