Additionally, there is some evidence to suggest a gradient effect, with increasing duration of educational experiences in rural settings, although the number of studies is small and limited to evaluating single programmes.
The median duration of educational training to become a radiographer was 2.5 years (IQR: 2 3 years) and the median time of experience performing mammography studies was 8 years (IQR: 2 18).
There is no consensus on the ideal duration of educational intervention studies,[ 18] though six months is the median duration of trials reviewed by Wensing,[ 32] Ideal duration is a balance between the time needed to effect change, whilst avoiding the danger of deterioration if the time scale were too prolonged[ 18].
In the next step of the analysis, we corrected the raw scores on all dimensions of the CQ Index for each institution, for the characteristics of the residents (age, duration of stay, educational level, health status) and interviewers (age, educational level, sex and previous interview experience [ 22]) that were found to be significant.
There were statistically significant differences among the subgroups of inadequate, marginal and adequate health literacy with respect to age, gender distributions, duration of DM, educational attainment, household income, and self-rated understanding of health education and instructions (Table 1).
Educational level was divided into three categories according to duration of education: <= 9 years, 10 12 years, and longer than13 years.
The duration of the educational intervention ranged from one to ten sessions.
The duration of the educational intervention ranged from 1 to 10 sessions.
Depression had a significant relation with cause of infertility, duration of infertility, educational level, and job of women.
Type of facility, gender, referral, duration of enrolment, educational status, income level, and type of marital status were most related with responsiveness domains.
Of those studies reporting the duration of their educational interventions, the shortest intervention took two hours and the longest took seven 4-hour sessions (28 h).
