Perception that "everything requires a lot of effort": transcultural SCL-25 item validation.

This brief report illustrates how the migration context can affect specific item validity of mental health measures. The SCL-25 was administered to 432 recently settled immigrants (220 Haitian and 212 Arabs). We performed descriptive analyses, as well as Infit and Outfit statistics analyses using WINSTEPS Rasch Measurement Software based on Item Response Theory. The participants' comments about the item You feel everything requires a lot of effort in the SCL-25 were also qualitatively analyzed. Results revealed that the item You feel everything requires a lot of effort is an outlier and does not adjust in an expected and valid fashion with its cluster items, as it is over-endorsed by Haitian and Arab healthy participants. Our study thus shows that, in transcultural mental health research, the cultural and migratory contexts may interact and significantly influence the meaning of some symptom items and consequently, the validity of symptom scales.

Time trends of incidence rates of thyroid cancer in Israel: what might explain the sharp increase.

BACKGROUND: Worldwide changes in the incidence, histological type, and prognosis of thyroid cancer (TC) have been observed. Regional differences in the spectrum of TC may be related to genetic factors, ionizing radiation, lifestyle, and nutritional iodine, as well as to the availability of medical services. METHODS: Analysis of records of 5864 TC patients (diagnosed between 1982 and 2001), retrieved from the Israel National Cancer Registry. RESULTS: The age-standardized incidence rate (ASR per 100,000 persons) of TC among Jewish women in 2001 was 12.45 (higher than generally reported in the world) and 3.68 among Jewish men. There was a significant increase in the ASR for TC between 1982 and 2001 in the Jewish population (by 101% among women and by 25% among men, p < 0.01 for both), mainly due to papillary carcinoma. TC incidence increased in the non-Jewish population from 2.33 to 6.02 in women (p < 0.05) and from 1.13 to 2.49 in men (p > 0.05). TC incidence was similar among immigrants from Europe and America arriving in Israel before 1990 or after 1990 for both genders. An improved 5-year survival was noted in patients diagnosed between 1992 and 1996 in comparison to patients diagnosed earlier: 1982-1986 (86% versus 78%, p < 0.01). CONCLUSIONS: A marked increase in TC incidence over the last two decades (mainly due to papillary carcinoma) has been noted in different Israeli subpopulations, being the highest in Jewish women. The increase trends were similar regardless of gender or ethnicity. The reasons for this rise in TC incidence and improvement in the survival are probably multifactorial and may relate partly to increased diagnostic vigilance and changes in clinical practice.

Premigration exposure to political violence among independent immigrants and its association with emotional distress.

Although the distinction between independent immigrants and refugees has an impact on policy, services, and public opinion because it implies differences in resettlement needs, few recent studies have documented the validity of this assumption. In this population-based survey of recent migrants in Quebec (N = 1871), immigration status (refugee, independent, or sponsored immigrant) is examined in relation to premigration exposure to political violence and refugees' emotional distress, assessed with the SCL-25. A higher percentage of refugees reported exposure to political violence in their homeland, but the percentages of exposed independent (48%) and sponsored (42%) immigrants were unexpectedly high. Emotional distress was significantly higher among Chinese respondents who had witnessed acts of violence and in subjects from Arab countries who reported persecution. These results suggest that service providers and policy makers should not assume that independent immigrants have not been exposed to political violence before their migration.
