5.2 Limitações e Futura Investigação
A primeira limitação deste estudo centra-se no facto de ter sido inquirida uma amostra de conveniência cuja representatividade pode ser questionável, o que poderá reprimir a representatividade desta amostra comparativamente ao universo. A segunda limitação reporta à dimensão da amostra, uma amostra de maior dimensão poderia permitir estudar com maior profundidade as perceções da liderança responsável no compromisso afetivo, comportamentos de cidadania organizacional e desempenho individual. Outra limitação centra-se na recolha de dados, dado que realizada num único momento temporal, o que pode implicar risco de contaminação pela variação do método comum (Posakoff, MacKenzie, Lee, & Podsakoff, 2003). Um estudo longitudinal poderia contribuir para novos conhecimentos, através da análise de mudanças nas caraterísticas dos elementos amostrais, tendo em conta as condições ocorrentes ao longo do tempo. Uma outra limitação desta investigação refere-se à condição de terem sido inquiridos apenas colaboradores subordinados e não líderes. Seria interessante perceber se os líderes se consideram como líderes responsáveis e se desenvolvem os comportamentos e atitudes aqui estudados. Ou mesmo perceber qual a sua perceção perante os seus subordinados no que ao compromisso
44 afetivo, comportamentos de cidadania organizacional e desempenho individual diz respeito. A última limitação alude aos métodos estatísticos utilizados, sendo que análises mais robustas poderiam compor esta investigação.
Adicionalmente, apesar das limitações deste estudo, estas permitem deixar em aberto alguns pontos de partida para futuras investigações. Existe, ainda, um longo caminho a percorrer no estudo da liderança responsável em contextos organizacionais, escasseando os estudos empíricos, como verificado na literatura, que relacionem esta temática da liderança responsável com outros construtos e que reforcem os resultados esperados teoricamente deste tipo de liderança. Sugere-se, assim, que sejam estudadas diferentes relações entre a liderança responsável e outros construtos, como é caso do Engagement, da (In)segurança no Trabalho, da Virtuosidade Organizacional ou da Satisfação Organizacional. Sugere-se, também, que se realizem estudos empíricos focados em amostras de diferentes climas organizacionais, em setores específicos e outros contextos culturais, tentando-se, desse modo, aferir se as perceções de liderança responsável também ocorrem em diferentes climas organizacionais mais ou menos satisfatórios, se podem suceder em outros setores, como os casos dos setores da Educação, da Administração Pública ou do Turismo.
Por último, sugere-se que em investigações futuras se promova o uso de diferentes e mais complexas técnicas estatísticas, como é exemplo do modelo de equações estruturais, onde se estudaria as relações simultâneas entre as várias dimensões dos modelos.
