The Impact of Engagement Processes on the First Appointment Attendance Rate at a Regional Outpatient Psychological Trauma Service.

The effectiveness of simple measures to increase attendance at first appointments is briefly reviewed. The Family Trauma Centre’s remit and pre-study engagement process are described. The perceived idiosyncratic aspects of inviting people suffering from psychological trauma to attend a clinical service are noted as contributory factors in initially tolerating a high first appointment DNA rate. Three new initial engagement processes are then described and results of their application to 30 referrals in total are presented. The overwhelming finding is that paying close attention to any of the three initial engagement processes significantly increases first appointment attendance. Based on these findings the Centre developed a new initial engagement protocol.. The principle that services should pay more attention to their engagement processes than on the characteristics of their client groups when seeking to reduce first appointment DNA rates is supported.

Modelling attribute non-attendance in choice experiments for rural landscape valuation

Non-market effects of agriculture are often estimated using discrete choice models from stated preference surveys. In this context we propose two ways of modelling attribute non-attendance. The first involves constraining coefficients to zero in a latent class framework, whereas the second is based on stochastic attribute selection and grounded in Bayesian estimation. Their implications are explored in the context of a stated preference survey designed to value landscapes in Ireland. Taking account of attribute non-attendance with these data improves fit and tends to involve two attributes one of which is likely to be cost, thereby leading to substantive changes in derived welfare estimates.
