Willingness, concerns, incentives and acceptable remuneration regarding an involvement in teaching undergraduates - a cross-sectional questionnaire survey among German GPs

Table 5 Logistic regression analyses predicting a general interest to be involved in teaching undergraduates (vs. no interest) (2 models: one including and one excluding GPs already teaching undergraduates)

	Model 1 (including GPs already teaching undergraduates, N = 280) (Nagelkerkes R² = 0.471)		Model 2 (excluding GPs already teaching undergraduates, N = 225) (Nagelkerkes R² = 0.468)
Variables included in the model (stepwise forward LR)	Odds Ratio OR (95% CI)	p	Odds Ratio OR (95% CI)	p
Age groups (vs. <= 40 years)		< 0.001		< 0.001
41 to 50 years	0.57 (0.21–1.53)	0.266	0.67 (0.25–1.82)	0.436
51 to 60 years	0.33 (0.13–0.83)	0.018	0.35 (0.14–0.89)	0.028
> = 60 years	0.04 (0.01–0.15)	< 0.001	0.03 (0.01–0.11)	< 0.001
Any memberships in professional associations (vs. no membership)	1.97 (1.05–3.70)	0.035	–	–
“rather high” or “very high” self-perceived continuing education activities in comparison to colleagues (dichotomized, vs. “very low”/“rather low”/“average”)	3.42 (1.79–6.55)	< 0.001	2.82 (1.41–5.65)	0.003
Wish to intensify continuing education activities: “rather yes”/“definitely yes” (dichotomized, vs. “definitely not”/“rather not”)	1.95 (1.03–3.68)	0.040	2.00 (1.00–3.99)	0.049
Already has experiences with any kind of teaching activity (vs. not)	10.97 (5.35–22.49)	< 0.001	11.28 (4.85–26.20)	< 0.001

Further variables considered: has children in the household currently (yes vs. no), has the permission to train residents (yes vs. no), a resident is working in the practice (yes vs. no), legal structure of the practice (single practice/joint practice/medical care center), practice environment (big city vs. small town/rural area), average effective work time per week (in hours)
Variables not considered despite univariable differences: years since (first) medical specialist exam (reason: correlation with age r = .94), years until retirement (reason: correlation with age r = −.93), years having an own practice (reason: correlation with age r = .81)
