As noted by Wise and Kong ([2005]), one limitation of self-reporting is that it is difficult to ascertain how truthfully the students respond to the questionnaires.
A second problem with using self-report is that participants are defining self-harm for themselves.
The reason for including this self-report is that internalizing symptoms in children can be expressed by somatic complaints only (Campo et al. 2004).
Another source of measurement error, apart from inaccuracies in self-report, is that the folate content of food changed over time.
The problem with self-reporting is that participants' responses may reflect intentionally or unintentionally perceived desirable responses or an attempt to inflate or minimize reports of behaviors.
(2007) recently argued that, 'the major difference between indirect measures and self-reports is that indirect measures provide a proxy for the activation of associations in memory, whereas self-reports reflect the outcome of validation processes.' (p. 187).
The major, and unavoidable, limit of our study for validating the self-reports is that we can only validate the tests performed within the screening programme, not those performed privately or in other settings that have no registries, nevertheless we do not see any reason for which women should preferentially forget the tests performed in a screening program or in another provider.
Undoubtedly, it can be argued that self-reporting is at least as necessary to an effective scheme of criminal law enforcement in this area.
Second, the link depended on self-reported food intake – and self reports are not always that reliable.
Another problem is that self-reporting is not always accurate — maybe church-goers hesitate to report bad behavior.
Most importantly, we managed to demonstrate that the current mood, as measured by self-report, is a factor that affects the patterns of effective cortical connectivity.
