This is a controversial study from Taiwan in terms of the results, but not the methodology.

Here are some fragments of a discussion of the study
Lung and Shu seem to be associated with the military in Taiwan and their subjects were from the annual intake of 140,000 young recruits. In that country military service is compulsory, hence the recruits represent the whole population of men. There are inevitably those who find military training almost unbearable, and many in Taiwan are diagnosed with adjustment disorder (a DSM mental health category). From these the authors selected 51 homosexuals, and 100 non-homosexuals. The controls were 124 recruits without adjustment disorder. Recruits with mental health issues other than these were eliminated from the study. It seems obvious that this study was possible because Lung and Shu were told by the authorities to study recruits who could not cope. However it means that the study of homosexuality is complicated by the adjustment disorder, which the authors had to take into account in the interpretation of their results. No other study has involved those with an accompanying mental condition like this. However it seems to me that the authors allowed for the adjustment disorder quite adequately. Overall the sample is much more representative than many in the West.
Social factors explain 62% of homosexuality
In their statistical model to explain homosexuality, Lung and Shu managed to explain 62% of the variance by parental factors and neuroticism level, ie 62% of homosexuality in their sample can be explained by parental factors and higher than normal levels of neuroticism. It is quite rare to get a figure as high as this when a sociological survey is involved. The relative strengths of the factors found important were Maternal Care 0.42, Maternal Protection 0.21, Paternal Care 0.21, Neuroticism 0.64. Paternal Protection, although individually the most important, and highlighted by the authors, exerted its effect through production of neuroticism. (General mental health itself did not directly affect development of homosexuality.) Unfortunately because of the peculiarities of modeling mathematics we cannot directly add the parental factors together to get an overall effect and compare them with the neuroticism result, but we can say other parental factors and neuroticism are roughly comparable in effect.
