Limitações e sugestões para investigações futuras

Esta investigação apresenta limitações que devem ser discutidas e ponderadas em investigações futuras. A primeira limitação está relacionada com o método de amostragem utilizado que, neste caso, foi um método não probabilístico, a amostragem por conveniência. Apesar das suas vantagens, ao selecionar elementos pela sua acessibilidade, voluntariado ou ocasionalmente, a amostra pode não ser representativa sendo necessário ter precaução na generalização da informação. Assim, investigações futuras deverão procurar utilizar outros métodos de amostragem.

Outra limitação a apontar prende-se com o facto de o método utilizado para recolher dados ter sido, exclusivamente, o questionário online. Ainda que este método tenha sido utilizado para recolher dados em diversos estudos sobre o fenómeno em estudo, a utilização de outros métodos no futuro pode complementar o conhecimento do tema, como por exemplo, a realização de experiências, entrevistas ou focus group. Para além disso, como o

56 questionário foi divulgado essencialmente nas redes sociais, há grupos de idades que não se conseguiu abranger de igual forma. No futuro, poderão ser utilizados, igualmente, questionários impressos e distribuídos a elementos que, tendencialmente, não utilizam tanto as redes sociais.

Este estudo solicitou, também, aos respondentes que as suas respostas fossem dadas tendo em consideração a sua experiência com o mobile shopping, que pode corresponder a um conjunto de episódios ao invés de um episódio específico de compra através de dispositivos móveis. Desta forma, os fatores contextuais que afetam o consumidor podem ter sido negligenciados. Investigações futuras poderiam procurar controlar os fatores contextuais, concentrando-se em situações ou episódios específicos.

Por fim, este estudo focou-se apenas no fator risco percebido, concluindo que explica uma reduzida variabilidade do abandono do carrinho de compras mobile. Futuras investigações devem incluir no seu modelo outros fatores para além do risco percebido. Como por exemplo, a inconveniência da transação, as promoções, a ansiedade do consumidor ou fatores culturais.

Como a investigação do tema do abandono do carrinho de compras mobile se encontra ainda pouco explorado, é fulcral que seja aprofundado o seu conhecimento. Seria interessante perceber como se comporta este fenómeno tendo em consideração diferentes tipos de produtos ou serviços, de forma a ter um estudo com conclusões mais focadas.
